IMG_20190310_101428_486~2

On behalf of QGIS.ORG and the whole community, I’m would like to extend our thanks and congratulations to all the local volunteers who helped to make the event happen, with special thanks to Luigi “Ginetto” Pirelli, who spearheaded the effort. The event, which included a full week of workshops, a user conference, and contributor meeting, marked another milestone in the history of QGIS.

It was possibly the largest meeting we have had to date. It especially gratifying seeing more diversity and new faces. Our inclusive and welcoming community has always been a point of pride and it was amazing seeing how newcomers easily and pleasantly integrating in the community, producing good and tangible results within just a few days.

Many decisions were made, many discussions were fruitfully concluded, many tortillas were eaten, plans were laid out. These events are critical for preparing the way for the future of the QGIS.ORG project.

Our heartfelt thanks to all who donated their time and intellect, and to the many donors and sponsors to make all this possible.

See you in Bucharest next August, for the 23rd QGIS meeting!

QGIS.ORG

End of life notice: QGIS 2.18 LTR

257901067_158842QGIS 3.4 has recently become our new Long Term Release  (LTR) version. This is a major step in our history – a long term release version based on the massive updates, library upgrades and improvements that we carried out in the course of the 2.x to 3x upgrade cycle.

We strongly encourage all users who are currently using QGIS 2.18 LTR  as their preferred QGIS release to migrate to QGIS 3.4. This new LTR version will receive regular bugfixes for at least one year. It also includes hundreds of new functions, usability improvements, bugfixes, and other goodies. See the relevant changelogs for a good sampling of all the new features that have gone into version 3.4

Most plugins have been either migrated or incorporated into the core QGIS code base.

We strongly discourage the continued use of QGIS 2.18 LTR as it is now officially unsupported, which means we’ll not provide any bug fix releases for it.

You should also note that we intend to close all bug tickets referring to the now obsolete LTR version. Original reporters will receive a notification of the ticket closure and are encouraged to check whether the issue persists in the new LTR, in which case they should reopen the ticket.

If you would like to better understand the QGIS release roadmap, check out our roadmap page! It outlines the schedule for upcoming releases and will help you plan your deployment of QGIS into an operational environment.

The development of QGIS 3.4 LTR has been made possible by the work of hundreds of volunteers, by the investments of companies, professionals, and administrations, and by continuous donations and financial support from many of you. We sincerely thank you all and encourage you to collaborate and support the project even more, for the long term improvement and sustainability of the QGIS project.

User question of the Month – Feb’19 & answers from Jan

In January, we wanted to learn more about if and how QGIS users contribute back to the project. We received 299 responses from all over the world:

user_survey_january_map

55% of responders have contributed to the project in the past:

user_survey_january_1

Responders who stated that they had contributed to QGIS were asked to specify what kind of contributions they had provided. This question was multiple-choice. Time contributions are generally more common than financial contributions. 30% of responders helped by creating reproducible bug reports and 24% implemented improvements themselves. The most common financial contribution are personal donations to QGIS.ORG at 17%.

Membership in user groups, contracting developers / documentation writers / translators, or having a support contract with a QGIS support provider are less common amongst responders:

user_survey_january_2

Responders who stated that they had not contributed to QGIS most commonly stated that they didn’t know how to contribute (26%), while lacking financial resources were only raised by 10% of responders:

user_survey_january_3

New question

This month, we’d like to know which plugins you think should be advertised as “featured” on the official QGIS plugin repository.

The survey is available in English, Spanish, Portuguese, French, Italian, Ukrainian, Danish, and Japanese. If you want to help us translate user questions in more languages, please get in touch!

User question of the Month – Jan19 & answers from Dec

In December, we wanted to know what QGIS.ORG should focus on in 2019.

Portuguese

Based on these results, in today’s PSC meeting, we’ve decided that the 2019 grant programme will be focusing on bug fixing and polishing existing features. So thanks to everyone who provided feedback!

New question

This month, we’d like to know if you have ever contributed to improving QGIS and – if yes – how. As you’ll see, there are many different ways to contribute to QGIS, so please go ahead and take the survey.

The survey is available in English, Spanish, Portuguese, French, Italian, Ukrainian, and Danish. If you want to help us translate user questions in more languages, please get in touch!

User question of the Month – Dec 18 & answers from Nov

It’s December and that means it is time to plan for the next year. Planning also means preparing a budget and to do so, we would like to learn more about what you think QGIS.ORG should focus on: features or bug fixing and polishing? Therefore, we invite you to our QGIS user question of December 2018.

We also have localized translated versions of this questionnaire for our French-speaking and Portuguese-speaking users.

Your answers in November

In November, we wanted to know which version of QGIS you use.

Results of the MacOS bug fixing initiative

Thanks to your donations, we were able to hire core developers to focus on solving Mac OS specific issues for QGIS. More than 30 MacOS QGIS users donated a little more than 3000 € for this bug fixing round.

After an effort of triage and testing, here is what has been achieved:

Unfortunately, some issues remain. Mainly, the text being rendered as outlines in PDF export (https://issues.qgis.org/issues/3975) remains for now. It might be fixed in a following effort.

Thanks to all donors who helped in this effort and to Denis Rouzaud as a core developer who spent a lot of time investigating and fixing these issues!

User question of the Month – Nov 18

QGIS 2.18 is the third LTR since we started this effort back in 2015 and next year will see the first LTR of QGIS 3. On this occasion, we want to learn more about our users and which versions of QGIS they use. Therefore, we invite you to our QGIS user question of the month.

Report back on the 20th QGIS Hackfest in Zanzibar

 

 

This post summarizes personal reports of community members who attended the 20th Hackfest in Stone Town, Zanzibar the week before the FOSS4G in Dar Es Salaam.

Report from Matteo Ghetta

QGIS developers spent 3 days in the beautiful island of Zanzibar were they worked on bug fixing, improvement of new features and documentation enhancements. It is extremely important for developers to meet together and spend some days working side by side given that the geographical distribution is very wide.

Thanks to the (local government & Yves Barthelemy) we had the chance to visit the Land Mapping Commission in Stone Town: It has been an amazing experience for both developers and local council. Moreover developers visited the SUZA (University of Zanzibar) and saw the local infrastructure and GIS related workflow.

  • I have merged many PR of the documentation
  • Many old and not old issues have been closed or the author has been pinged
  • Many new additions to the documentation both small corrections and new sections from scratch
  • A new version of DataPlotly released
  • A small presentation of DataPlotly to the QGIS crew

Report from Mario Baranzini

I spent one day of the Hackfest contributing to the SLYR project, improving the conversion of LAB colors. SLYR (https://github.com/nyalldawson/slyr) is a project started and almost entirely developed by Nyall (which was not present to the Hackfest) which aims to provide tools to extract and convert symbols from ESRI .lyr and .style files and use them in QGIS. Nyall has recently worked hard on the project and perhaps soon sponsorship will allow further development.

Around this theme there is a keen interest. Even during the FOSS4G there has been discussion of the conversion of ESRI symbols and there was also a presentation of how the conversion in Israel is currently managed.

During the rest of the hackfest, I worked on the implementation of the new QField file selector.

Report from Denis Rouzaud

Report from Tim Sutton

Firstly let me thank the QGIS project for contributing to my travel and accommodation costs – I am most grateful for the support! This hackfest was special for me because it is the first hackfest in an African country. As an African born person living in the interface between “first world” and “third world”, I have always had a particular social agenda with QGIS: To bring spatial tools to support responsible and sustainable management of our world. There is a huge technological and skills divide between Europe and less developed societies where QGIS can be a valuable social enabler in helping to advance the standard of living and quality of life. Hosting a hackfest in an environment where we don’t have tree cadastres, street furniture cadastres and every aspect of civilian life mapped and systematised is an important way to build empathy and understanding in our QGIS core community members for a broader cross-section of our user base. Having the opportunity to meet with users from ZMI (the Zanzibar Mapping Initiative) and students from the local university was a really uplifting experience. ZMI are building the national cadastre from the ground up using QGIS, PostGIS and UAV mapping. We were privileged to have a number of Zanzibar residents join us on the hackfest and get to experience just how appreciative they are, first hand.

There were a number of interesting topics that arose during the hackfest which I will try to summarise here:

Certification:

We held an extended meeting on the QGIS Certification Programme, mainly detailing how we should go about the review process for onboarding new organisations.

Mac OS Build:

I spent quite a bit of time struggling with my MacOS build on QGIS. It’s definitely an area of the project that needs more work as the process can be non-trivial and the brew based formulas quickly become outdated.

QField Show and Tell:

Matthias showed off the latest version of QField and all the hard work they have been putting into the QGIS mobile client. This Android based version of QGIS for mobile data gathering is a really great project and is getting more and more useful with each release. There was also a translation sprint for QField during which I translated it to Afrikaans.

QField Autobuilds:

Denis and Matthias showed off the work they have done to automate the .apk builds for QField. Their system combines Travis and some git hooks to automatically build .APK’s whenever a pull request os made or a tag is made. See the QField travis for details: https://github.com/opengisch/QField/blob/master/.travis.yml

Plotly plugin:

Matteo Ghetta showed off the latest capabilities of the Data Plotly plugin for QGIS 3. The plugin supports the creation of a wide assortment of charts from your layer’s attribute data. See the plugin homepage here for examples and more detail: https://github.com/ghtmtt/DataPlotly 

Governance:

I took the opportunity to sign off the statute changes from 2017 general meeting. This was my last official act as outgoing project Chair. I was also extremely humbled to be awarded an Honorary PSC membership during the FOSS4G2018 conference.

TimRecievesHonoraryPSCMembership
Easter Eggs:

I contributed a couple of new easter eggs to QGIS. While easter eggs are fun, the data behind these hidden tools provide an important history of the project. I took the opportunity of having many long-time QGIS community members around the dinner table to collate all the previous QGIS meet-up dates. You can view this as a map here: https://github.com/qgis/QGIS/blob/master/resources/data/qgis-hackfests.json 

The spatial clustering of these events shows that going to Zanzibar and getting out of our geographical comfort zone is a really useful endeavour.

Report from Paolo Cavallini

During the HF in Zanzibar I mainly worked on:

  • Plugins: I cleaned up the queue of unapproved plugins, contacting all individual authors, fixing what was possible and deprecating the worst cases; we also solved a long standing issue with a contentious plugin
  • Issues: I examined many tickets, especially those waiting for feedback
  • Training certification: through a very productive meeting we defined clear rules for accepting certifying organizations, with the main aim of driving people to actively support the project:
    • in the application process, the proponent should explain what are his contribution to QGIS project
    • following an initial review, the application will be sent to local QGIS groups for their opinion, which should take place in less than one monthly; where there is no user group, the responsibility will fall entirely on PSC shoulders
    • the training material for each course should be released with a free license, and a review will be done; if the material is not of adequate quality, this is a cause for refusal
    • then PSC will take a decision and publish the contributions as stated by the proponent, for transparency
  • Other meetings helped focusing on our mission, defining the relationship between volunteer and paid work, and other
  • I visited the Land Mapping Commission and the University, soliciting a tighter cooperation with QGIS project.

Report from Admire Nyakudya

During the heck fest in Zanzibar, I mainly worked on porting some common plugin we use to QGIS 3. The plugins I mainly worked on were Cogo Parcel plugin and Sg Diagram downloader. We visited the Zanzibar mapping agency and interacted with the people who were working on capturing cadastral data using QGIS and explained them about the COGO Parcel plugin which streamlines capturing cadastral boundaries in QGIS and storing the results in a PostgreSQL database. To summarise the work I was working on during the heck fest.

  • Port Cogo Plugin from QGIS 2 to make it compatible with QGIS 3. This has been achieved and now awaiting one of my team members to approve the pull request.
  • Expand functionality being offered by the COGO Parcel plugin to include the new reporting framework in QGIS 3.
  • Investigate ways to generate projects on the fly after talking to Matteo and seeing the work he has done with QGIS project generator.

I also went to the Zanzibar university to see ways in which QGIS is being used in the local university and how students are integrating drone imagery with QGIS.

Report from Matthias Kuhn

The highest value of hackfests is actually to meet and greet and discuss ideas and bigger plans. There is a lot of communication on a high bandwidth channel (also known as face-to-face) that strengthens the community. This helps to quickly overcome technical problems sometimes. Or to give someone some tips and tricks you normally wouldn’t come to (e.g. optimizing a git workflow) that results in a long-term gain because of sustainable productivity improvements. I tend to walk around once in a while and just randomly bump into people where I – more or less successfully – try to help them solve their issues or discuss approaches. In the same area, there is the possibility to informally discuss plans about organization, workflows and strategies. The concept of an LTR was to a big degree discussed and built at a hackfest in Essen some years ago. This year there was a very interesting discussion about the topic LTR. For how much time the “long” in the term “long term release” should stand, about the life cycle of releases and of long-term releases. One of the important things when it comes to this question is what organisations think and do – because, in the end, it is mostly for organisations that the LTR exists – and how development resources can be assigned to the task of keeping a high quality of an LTR during its whole lifetime. There are no conclusions yet, but synchronizing on these ideas is often the seed for tomorrow’s exciting changes.

We were also visited by a group of students from the local university. It was really refreshing to talk to them about open source and QGIS and how we work and what the challenges of spatial data and GIS infrastructure are on an island like Zanzibar.

Feature-wise, the main thing I worked on feature wise was a new snap to grid functionality that is available for digitizing tools. It allows configuring a precision for vector layers. Whenever a new node is added or an existing one is edited on this vector layer, it will be automatically placed on this grid. Normally this is used to force the objects on a layer to something like cm or mm resolution.

And then, of course, I did my daily bunch of (mostly volunteer) pull request reviewing, some code cleanup and some bugfixes.

Report from Marco Bernasocchi

https://photos.app.goo.gl/seX2kSJ9vKxKBZt58

The Zanzibar hackfest was a special one for me, my first hackfest as QGIS.org co-chair. My main goal was definitely to get as much information out of Tim as possible so that I wouldn’t have to keep on bugging him all time 🙂

Beside that, multiple meetings where planned to which I took part, as Paolo already explained, we had very good meetings about:

  • Certifications meeting
  • Trademark discussion
  • Creating a membership system that allows entities that are not allowed to budget sponsoring money to instead become paying members.
  • Other meetings helped focusing on our mission, defining the relationship between volunteer and paid work, and other

On the first two days, we were joined by a largish group of local students to whom I explained how the structure of QGIS.org works and where they could help. I also helped them choosing a task to work and mentored them.

As I mentioned before, I spent a lot of time asking a lot of questions to Tim to get the biggest possible knowledge transfer about running QGIS.org and some time choosing and booking restaurants for our evening “meetings”

On the technical side, I worked with Mario on a new implementation of the QField File selector.

After everybody left, the OPENGIS.ch team stayed one day longer and introduced Mario to the real Brighton-style hackfest with take-away pizza 😉

 

QGIS 3.4 Madeira is released!

We are pleased to announce the release of QGIS 3.4 ‘Madeira’! Madeira was the location of our developer meeting in February 2018.

Windows installers and Ubuntu/debian binaries are already out, and all the packagers are actively preparing packages for the other operating systems. We’ll keep you updated when different packages and installers become available.

QGIS 3.4 comes with tons of new features, as you can see in our visual changelog.

QGIS 3.4 will become the first LTR of version 3. Based on our current plans, 3.4 will replace 2.18 as LTR in February 2019.

We would like to thank the developers, documenters, testers and all the many folks out there who volunteer their time and effort (or fund people to do so). From the QGIS community we hope you enjoy this release! If you wish to donate time, money or otherwise get involved in making QGIS more awesome, please wander along to qgis.org and lend a hand!

QGIS is supported by donors and sponsors. A current list of donors who have made financial contributions large and small to the project can be seen on our donors list. If you would like to become and official project sponsor, please visit our sponsorship page for details. Sponsoring QGIS helps us to fund our six monthly developer meetings, maintain project infrastructure and fund bug fixing efforts. A complete list of current sponsors is provided below – our very great thank you to all of our sponsors!

QGIS is Free software and you are under no obligation to pay anything to use it – in fact we want to encourage people far and wide to use it regardless of what your financial or social status is – we believe empowering people with spatial decision making tools will result in a better society for all of humanity.

MacOS specific bug fixing campaign

If you are a MacOS QGIS user, you are probably bothered by some MacOS specific bugs. These are due to the fact that we have fewer QGIS developers working on the MacOS platform and there are additional MacOS specific issues in the underlying qt5 library.

Nevertheless, we found a developer, Denis Rouzaud, who wants to specifically look into investigating and hopefully solving several of these issues. If you are a MacOS user and care about a better QGIS experience on this platform, we invite you to financially support this effort. As a private person, and for smaller amounts, please use the usual donation channel – if you are a company or organization and want to contribute to this specific effort, please consider becoming a sponsor. In any case – please add “MacOS bug fixing campaign” as a remark when donating/sponsoring or inform [email protected] about your earmarked donation.

This effort runs from the 14th September 2018 until the 3.4 release date, due on October 26, 2018. See the QGIS road map for more details about our release schedule.

Specific issues that are looked into, are:

issue priority subject
11103 1 Support for retina displays (HiDPI)
17773 1 No Retina / HiDPI support in 2.99 on osx
19546 1 QGIS 3 slow on macOS at high resolutions
19524 1 [macOS] Map canvas with wrong size on QGIS 3.2.1 start up
19321 2 Map Tips on Mac doesn’t display the content correctly
19314 1 3.2 crashes on startup on a Mac
19092 2 Measure tool on a Mac uses the top right corner of the cross hair cursor instead of the centre
18943 3 QGIS Server on MacOS X High Sierra
18914 3 [macOS] Plugin list corrupted by wrongly placed checkboxes on Mac
18720 2 QGIS 3.0.1 crashes on Mac
18452 3 Snapping options missing on Mac
18418 2 Scroll zoom erratic on Mac trackpad
16575 3 QGIS 2.18.7 crashes on macOS 10.12.4 when undocking the label panel
16025 2 [macOS] Control feature rendering order will crash QGIS
3975 2 PDF exports on OSX always convert text to outlines

Thank you for considering to support this effort! Please note that some issues may also exist due to up-stream issues in the qt library. In such a case, it can’t be guaranteed if and how fast, such an issue can be fixed.

QGIS Server certified as official OGC reference implementation

We are very excited to announce that QGIS Server has been successfully certified as a compliant WMS 1.3 server against the OGC certification platform, and moreover, it is even considered as a reference implementation now!

This is the first step on our roadmap of having a fast, compliant and bullet proof web map server that is straightforward to publish from a classical QGIS project.

What does it mean?

Having a certified server means that QGIS Server successfully passes the automated and semi automated tests that ensure we are 100% compliant with the standards. That means you can trust QGIS to be used by any WMS client seamlessly.
Moreover, that certification is now powered by a continuous integration system that checks every night in developement versions if we still pass the tests.

Daily compliance reports are available on the new test.qgis.org website.

What’s next?

Building the automated testing platform and getting officially certified was only the first step. We now are starting to certify the WFS services, thanks to the latest grant application program support.

We also want QGIS server development to be performance-driven. The following projects are particularly relevant:

  • MS-Perf produces benchmark reports with MapServer and GeoServer.
  • graffiti  and PerfSuite tools have been designed to create a really light tool, easy to enrich with new datasets and performance tests, and easy to integrate in continuous integration systems. It compares QGIS-ltr, QGIS-rel and QGIS-dev nightlies for the same scenarios in details and produces html reports. It can also graph performance history for the development version to track regressions or improvements.

Many thanks to the supporters and voting members that helped bootstrap all those testing platforms and offer them to the community.

If you want to support or give a hand on the QGIS desktop client side, we think that area would deserve some love too!

QGIS 3.2 Bonn is released!

We are pleased to announce the release of QGIS 3.2 ‘Bonn’. The city of Bonn was the location of our 16th developer meeting.

splash32.png

This is the second release in the 3.x series. It comes with tons of new features (see our visual changelog).

Packages and installers for all major platforms are available from downloads.qgis.org.

We would like to thank the developers, documenters, testers and all the many folks out there who volunteer their time and effort (or fund people to do so). From the QGIS community we hope you enjoy this release! If you wish to donate time, money or otherwise get involved in making QGIS more awesome, please wander along to qgis.org and lend a hand!

QGIS Grant Programme 2018 Results

We are extremely pleased to announce the winning proposals for our 2018 QGIS.ORG grant programme. Funding for the programme was sourced by you, our project donors and sponsorsNote: For more context surrounding our grant programme, please see:

The QGIS.ORG Grant Programme aims to support work from our community that would typically not be funded by client/contractor agreements, and that contributes to the broadest possible swathe of our community by providing cross-cutting, foundational improvements to the QGIS Project.

Voting to select the successful projects was carried out by our QGIS Voting Members. Each voting member was allowed to select up to 6 of the 14 submitted proposals by means of a ranked selection form. The full list of votes are available here (on the first sheet). The second sheet contains the calculations used to determine the winner (for full transparency). The table below summarizes the voting tallies for the proposals:

voting_results_2018

A couple of extra notes about the voting process:

  • The PSC has an ongoing program to fund documentation so elected to fund the QGIS Training Manual update even if this increases the total funded amount beyond the initial budget.
  • Although the budget for the grant programme was €25,000, the total amount for the winning proposals is €35,500. This increase is possible thanks to the generous support by our donors and sponsors this year.
  • Voting was carried out based on the technical merits of the proposals and the competency of the applicants to execute on these proposals.
  • No restrictions were in place in terms of how many proposals could be submitted per person / organization, or how many proposals could be awarded to each proposing person / organization.
  • Voting was ‘blind’ (voters could not see the existing votes that had been placed).

Of the 45 voting members, 29 registered their votes 17 community representatives and 12 user group representatives.

On behalf of the QGIS.ORG project, I would like to thank everyone who submitted proposals for this call!

A number of interesting and useful proposal didn’t make it because of our limited budget; we encourage organizations to pick up one of their choice and sponsor it.

QGIS User Conference 2018

This year’s QGIS User Conference will be embedded within the FOSS4G conference. That means that you should refer to the FOSS4G web site for all registration and event details with the exception of the QGIS Hackfest (22-26 August) which follows our normal organisation procedure on the QGIS Wiki.

There are five main activities for QGIS Users to enjoy at the conference:

  1. The QGIS Hackfest: This is our twice-yearly meet up to work on and improve the QGIS code base. Come along to this event if you want contribute documentation, bug fixes, bug reports, features and other ideas for improvements to the QGIS project. The hackfest is a side event to be held on the island of Zanzibar and will happen before the main conference. Again refer to the QGIS Hackfest wiki page for details and to register.
  2. The Workshops: FOSS4G is always popular for the wide range of workshops presented. The workshop presentations are very often by the developers of the software being explained, which gives you a unique opportunity to talk face to face with the people using the software you are using. There will be a number of QGIS specific workshops at FOSS4G – you will be able to identify them easily on the mobile app that provides the conference programme by filtering on ‘QGIS’ in the workshops section. For a current list of all the workshops at the event please refer to: https://2018.foss4g.org/workshop-schedule/ 
  3. The Presentations: There will be a wide range of QGIS related presentations during the main conference. 17 QGIS related presentations have been registered. See https://2018.foss4g.org/programme/list-of-presentations/ for a full list of the conference presentations.
  4. The Academic Track: This year a large number of academic papers have been submitted, a good number of which relate to QGIS. Watch the conference web site for more details to be published soon!
  5. The QGIS Plenary / Panel Discussion: During the conference we will have an ‘Ask Me Anything’ session with QGIS developers and community members forming a panel to field any questions you might want to ask! This is a unique opportunity to find out more about the project, its roadmap or just come along to say ‘thank you’ to the dedicated team of community members who put so much work into making QGIS!

If you have not already registered for FOSS4G2018, do so now to enjoy early bird rates! Visit the Registration Page for more details! We are looking forward to meeting you in Dar es Salaam and Zanzibar!

About the FOSS4G2018 Conference

The annual Free and Open Source Software 4 Geospatial. (FOSS4G) conference is the largest community gathering focused on open source geospatial software. FOSS4G brings together developers, users, decision-makers and observers from a broad spectrum of organizations and fields of operation. Through six days of workshops, presentations, discussions, and code sprints, FOSS4G participants, learn, exchange, and create new collaborations, geospatial products, standards.

FOSS4G is a global conference, with attendees from around the world! Last year, Boston, USA was the host city, before that in 2016 it Bonn, Germany. Now is the time for Dar es Salaam, Tanzania! FOSS4G 2018 will host numerous workshops over 27 – 28 August with exciting keynotes and presentations at the Julius Nyerere International Convention Centre 29 – 31 August, and finally Code Sprints and community building events September 1 & 2. In addition to bringing together the FOSS4G community in Dar, the 21st QGIS Developer meeting will take place in Zanzibar (a short 60min ferry trip away!) the 22 – 26 of August – the Geospatial Savanna is on the rise in East Africa!

The vision for the conference is to make it as accessible and inclusive as possible, bridging the gaps between the various communities that make us so strong, to make us stronger. This will be achieved through a Travel Grant Program that will enable economically disadvantaged participants the opportunity to attend, covering travel, lodging and conference costs. This will be bolstered by an exciting conference program, taking the very best that the open source geospatial community can offer. This ranges from locating schools to the instrumentation of communities with cheap, open source, 3D printed weather stations that improve community resilience to climate change.

The theme for FOSS4G 2018 is “Leave No-One Behind”. We live in a world where our users and developers have the opportunity to make a difference to the lives of everyone, whether it’s those in extreme poverty looking for access to clean water, to those using routing algorithms to calculate the fastest route to work. Location and geography are at the heart of these challenges and a FOSS4G 2018 in Dar es Salaam will invigorate our existing projects, bringing them to new users and developers while supporting and nurturing the existing community.

New PyQGIS documentation

We are proud to announce our new dedicated documentation of the QGIS Python API (also called PyQGIS) which is now available at https://qgis.org/pyqgis:

While the QGIS API has long been documented, Python developers in the past had to work with the general C++ documentation that wasn’t always straightforward to use. The new PyQGIS documentation presents the API in an accessible pythonic manner.

Of course, creating a good API documentation from source code in an automated way, is not trivial. A key challenge was to automatically create Python bindings files (or SIP files). A custom Perl script known as “sipify” now enables us to automatically integrate the C++ documentation into the Python bindings and keep them up to date. Another challenge was to create the documentation itself using Sphinx. Two detailed reports containing all the technical details of the first and second generation of the documentation are available if you want to learn more about the underlying architecture.

This has been a really important infrastructure project for QGIS that has been made possible by support from our donors and sponsors, as well as the generous in-kind contributions of our community members.

Reports from the winning grant proposals 2017

While we are waiting for this year’s grant proposals to come in, it is time to look back at last year’s winning proposals and their results. These are the reports on the work that has been done within the individual projects:

QGIS 3D – Martin Dobias

Results are included in the QGIS 3.0 release. As proposed in the grant, a new 3D map view has been added together with GUI for easy configuration of 3D rendering. The 3D view displays terrain (either from a DEM raster layer or a simple flat area) with 2D map rendered on top of the terrain. In addition to that, vector layers can be rendered as true 3D entities: points may be visualized as simple geometric shapes or as 3D models (loaded from a file), polygons and linestrings are tessellated into 3D geometries. 2D polygons can be turned into 3D objects using extrusion, possibly with data-defined height – an easy way how to display buildings, for example. Data with 3D coordinates have the Z values in geometries respected. Although the 3D view is still in its early stages, it is already usable for many use cases. Hopefully this functionality will help to attract even more users to QGIS!

Improvements to relations – Régis Haubourg

Various improvements for deep relations with PostgreSQL were successfully added in QGIS 3.0:

Add consistency to UI controls – Nyall Dawson

We’ve unified all the various opacity, rotation and scale controls to use the same terminology and numeric scales. We’ve also updated ALL methods for setting opacity, rotation and scale within the PyQGIS API to use consistent naming and arguments, making the API more predictable and easy to use. Lastly, we’ve also added a new reusable opacity widget (QgsOpacityWidget) to the GUI library so that future code can (and 3rd party scripts and plugins) can follow the new UI conventions for opacity handling.

Extend unit test coverage for geometry classes – Nyall Dawson

We’ve extended the unit testing coverage for all the underlying geometry primitive classes (points, lines, polygons, curves, collections, etc) so that all these classes have as close to 100% unit test coverage as possible. In the process, we identified and fixed dozens of bugs in the geometry library, and naturally added additional unit tests to avoid regressions in future releases. As a result QGIS’ core geometry engine is much more stable. Furthermore, we utilised the additional test coverage to allow us to safely refactor some of the slower geometry operations, meaning that many geometry heavy operations will perform much faster in QGIS 3.0.

Processing algorithm documentation – Matteo Ghetta & Alexander Bruy

The new Help system is landed and already available: when opening a Processing algorithm and clicking on the Help button, the guide of the algorithm will be showed in the default browser.

Many of the QGIS Processing algorithm guides have been enhanced with pictures and new or enhanced descriptions. A consistency number of Pull Requests have been already merged and many others are in review. Just a few descriptions need to be still enhanced.

Currently all the QGIS algorithms have been described and all the PR in the doc repository have been merged (kudos to Harrissou for all the reviews!).

Right now the Help button of each Processing dialog will open the related page of the algorithm, BUT:

  • if the name of the algorithm is made by only ONE word (e.g. clip, intersection…), the help button will open the browser to also the correct section (that is, the user will see directly the description of the related algorithm)
  • if the name of the algorithm has >1 words (e.g. split polygon with lines, lines to polygon, ecc.) the Help button will open the correct page (so the algorithm GROUP) but is not able to go to the correct algorithm anchor. This is because sphinx converts “split with lines” in “split-with-lines” while QGIS system will always cast the words “split-with-lines” in “splitwithlines”. Not a big deal, but IMHO a pity.
    We are really too close to the solution.

So Processing Help system right now consists of:

  • QGIS algs -> documented
  • GDAL algs -> documented
  • GRASS -> documented (own docs)
  • Orfeo -> documented (own docs)
  • SAGA -> nothing documented

Thanks to QGIS Grants to provide this chance to give a big improvement to the Processing framework even if not in a coding way!


Last but not least, we had another project that was not part of the grant programme but was also funded by QGIS.ORG in 2017:

Python API documentation – Denis Rouzaud

QGIS Python API Documentation is created using Sphinx and this work is available on Github. The repo is a fork of QGIS’ one and has been merged in the meantime. The docs are available at qgis.org/pyqgis. It uses a new theme (sphinx_rtd_theme aka ReadTheDocs theme). Some improvements were brought in (not exhaustive):

  • QGIS theming with colors and icon
  • Foldable toctree
  • Summary of methods and attributes for classes
  • Module index (not available before)
  • Correct display of overloaded methods

Full Python signature in Docstring

In former SIP versions, it was not possible to use the auto generated signature if a Docstring already existed. This means any documented method could not have a signature created. Unfortunately for this project, the vast majority of methods in QGIS API are documented!

The source code of SIP was modified and theses changes got merged upstream. See rev 1788 to 1793 in SIP changelog. It will be released in upcoming 4.19.7 version. QGIS source code was modified accordingly to prepend auto generated Python signatures to existing Docstrings. Using a CMake configuration file for each module (core.sip.in, gui.sip.in, etc.) was required to avoid syntax errors when using former version of SIP (since bumping minimum version is not realistic).

Sipify adjustments

Many things were fixed in sipify script :

  • Creation of links to classes, methods
  • Handling/fixing of Doxygen annotations \see, \note, \param
  • Handling of code snippets: c++ vs Python. Only Python are shown.

Thank you to everyone who participated and made this round of grants a great success and thank you to all our sponsor and donors who make this initiative possible!

Preparing for the next LTR

Dear QGIS users,

As you know, QGIS 3 has recently been published. This version introduced big changes in  the code structure that, in addition to the new functionalities already exposed, makes our code base more modern and easier to expand and improve on in the future.

As a normal by-product of such a huge overhaul, these changes also triggered a series of new issues, that you, our users are helping to discover and document. Our objective is to eliminate the most important of these issues in time for what will be our next Long Term Release (LTR) – version 3.4. This release is scheduled for October 2018. The resources available from QGIS.ORG funds are limited, and we have already invested in QGIS 3.0 far more than we have done for any previous version.

Now is a great time for users, and particularly for power users, larger institutions and enterprises, to invest in QGIS bugfixing. You have a number of different options: donating your developers’ time or hiring a developer directly to resolve the bugs that annoy you most, sponsoring our foundation, or donating to QGIS.ORG.

Our targets are:

  • 20k€ within 2018-05-18 (for 3.2)
  • 40k€ within 2018-09-14 (for 3.4)

If you would like to help, feel free to contact us (preferably through the qgis-users or qgis-developers mailing list, or directly to [email protected]) for further details!

QGIS PSC

QGIS Annual General Meeting – 2018

Dear QGIS Community

 

We recently held our 2018 QGIS Annual General Meeting. The minutes of this meeting are available for all to view. As I have previously announced, I have decided to step down as chair of the PSC this year, so this post is my last official act as QGIS Chair. Thank you all for the kind words and deeds of support you gave me during my time as project chair.

I would like to welcome our new QGIS Board Chair: Paolo Cavallini, and our new QGIS Board Vice-Chair and QGIS PSC Member, Marco Bernasocchi. In case you are not familiar with Paolo and Marco, you can find short introductions to them below. I am pleased also to say that the project governance is in good hands with Richard Duivenvoorde, Jürgen Fischer, Andreas Neumann and Anita Graser kindly making themselves available to serve on the PSC for another two years. It is also great to know that our project founder, Gary Sherman, continues to serve on the PSC as honorary PSC member. Gary set the standard for our great project culture and it is great to have his continued presence.

QGIS has been growing from strength to strength, backed by a really amazing community of kind and collaborative users, developers, contributors and funders. I am looking forward to seeing how it continues to grow and flourish and I am excited and confident it will do so with Paolo acting as the project chair and representative. Rock on QGIS!

 

Paolo Cavallini

Paolo

I got involved in QGIS long ago, first as a user, then more and more deeply in various activities, initiating and supporting various plugins and core functions (e.g. GDAL Tools, DB Manager), opening and managing bugs, taking care of GRASS modules, handling the trademark registration, etc. I acted as Finance and Marketing Advisor for several years. Currently, I manage the plugin approval process. Motivation: It’s such a pleasure building up, in a truly cooperative and democratic way, together with truly intelligent people, a tool that enables people to freely do their job or pursue their interests, that I cannot resist helping as much as I can.

20180214_112925.jpg

I am an open source advocate, consultant, teacher and developer. My background is in geography with a specialization in geographic information science. I live in Switzerland in a small Romansh speaking mountain village where I love scrambling around the mountains to enjoy the feeling of freedom it gives me. I’m a very communicative person, I fluently speak Italian, German, French English and Spanish and love travelling. I work as director of OPENGIS.ch which I founded in 2011. Since 2015 I share the company ownership with Matthias Kuhn. At OPENGIS.ch LLC we (4 superstar devs and myself) develop, train and consult our client on any aspect related to QGIS. My first QGIS (to be correct for that time QuantumGIS) ever was “Simon (0.6)” during my BSc when the University of Zurich was teaching us proprietary products and I started looking around for Open Source alternatives. In 2008, when starting my MSc, I made the definitive switch to Ubuntu and I started working more and more with QGIS Metis (0.11) and ended developing some plugins and part of Globe as my Masters thesis. Since three years the University of Zurich invites me to hold two seminars on Entrepreneurship and Open Source. In November 2011 I attended my first Hackfest in Zürich where I started porting all QGIS dependencies and developing QGIS for Android under a Google Summer of Code. A couple of years and a lot of work later QField was born. Since then I’ve always tried to attend at least to one Hackfest per year to be able to feel first hand the strong bonds within our very welcoming community. In 2013 I was lucky enough to have a release named after a suggestion I saved you all from having QGIS 2.0 – Hönggerberg and giving you instead QGIS 2.0 – Dufour Beside my long story with QGIS as user and passionate advocate I have a long story as QGIS service provider where we are fully committed to its stability, feature richness and sustainable development. Furthermore, as WorldBank consultant, I am lucky enough to be sent now and then to spread the QGIS goodness in less fortunate countries. Motivation: One of my main motivation to be part of the PSC is to help QGIS keep this incredible growth rate by being even more attractive to new community members, sponsors and large/corporate users. To achieve this, the key is maintaining the right balance between sustainable processes (that guarantee the great quality QGIS has been known for) and an interesting and motivating grassroots project where community members can bloom and enjoy contributing in their most creative ways.
