QGIS Planet

Introducing new QGIS macOS packages

We now have signed packages for macOS. You can find these packages published on the official QGIS download page at http://download.qgis.org.

Rationale

In addition to being a very powerful and user-friendly open source GIS application, QGIS can be installed on different operating systems: MS Windows, macOS, various flavours of Linux and FreeBSD. 

Volunteers help with generating the installers for those platforms. The work is highly valuable and the scale of effort put into packaging over the years is often underappreciated. QGIS has also grown significantly over the years and so has its complexity to package relevant libraries and 3rd party tools to the end-users.

QGIS has been packaged on OSX/macOS for many years, making it one of the few GIS applications you can use on this platform. This is largely thanks to the tireless work of William Kyngesburye (https://www.kyngchaos.com/software/qgis/) who has shouldered the task of compiling QGIS and its dependencies and offering them as disk images on the official QGIS website. The packages for each new release are available within days for all supported macOS versions.

Unlike most other operating systems, macOS can only be run on Apple hardware. This is a barrier for developers on other platforms who wish to compile and test their code on macOS. For other platforms, QGIS developers have automated packaging, not only for the major releases but also for daily code snapshots (aka nightly or master builds). Availability of the daily packages has allowed testers to identify platform-specific issues, well before the official release.

Apple also has a system of software signing so that users can verify if the packages are securely generated and signed by the developers. Up until now, signed macOS packages were not available, resulting in users who are installing QGIS needing to go into their security preferences and manually allow the QGIS application to be run. 

A new approach

In October 2018, Lutra Consulting started their work on packaging QGIS for macOS. The work has been based on OSGeo tap on Homebrew. Homebrew is a ‘bleeding edge’ package manager similar to those provided by Gentoo or Arch Linux. The packages by Lutra bundle the various libraries and resources on which QGIS depends into a single QGIS.app application bundle.  The packages were made available in late 2018 for QGIS official releases and master. QGIS Mac users have eagerly tested and reported various issues and the majority of them were resolved in early 2019.

Following the successful launch of the prototype packages and in discussion with other developers, it was agreed to transfer the ownership of the packaging infrastructure and scripts (https://github.com/qgis/QGIS-Mac-Packager) to QGIS.org. Using the new infrastructure and OSGeo Apple developers certificate, all QGIS ‘disk images’ (installers) have been available since late May 2019.

What are the main difference between the new installers and the ones offered by Kyngchaos? The new installer offers:

  • 3 clicks to install: download, accept Terms & Conditionss, drop to /Application
  • All dependencies (Python, GDAL, etc)  are bundled within the disk image
  • Signed by OSGeo Apple certificate
  • Availability of nightly builds (master)
  • Scripts for bundling and packaging are available on a public repository
  • Possibility of installing multiple versions (e.g. 3.4 LTR, 3.8 and master) side-by-side

There are some known issues:

For a full list, see: https://github.com/qgis/QGIS-Mac-Packager

Further work

We hope that by providing the new installers, macOS users will have a better experience in installing and using QGIS. Ideally, with the availability of nightly builds and being more accessible to new users, more software bugs and issues will be reported and this will help to improve QGIS overall.

Maintaining and supporting macOS costs more compared with other platforms. As QGIS is one of the only viable GIS applications for macOS users in an enterprise environment, we encourage you and your organisation to become a sustaining member to help assure the continued availability and improvement of the macOS packages in the long term.

Future plans

In future we plan to migrate the packaging process to use Anaconda QGIS packages as the source for package binaries. We also would like to integrate macOS builds into the Travis-CI automated testing that happens whenever a new GitHub pull request is submitted so that we can validate that the macOS packages do not get any regressions when new features are introduced.

Conclusion

With this work, we now have nightly builds of the upcoming release (‘master’) branch available for all to use on macOS. We now have signed packages and we have an automated build infrastructure that will help to ensure that macOS users always have ready access to new versions of QGIS as they become available. You can find these packages published on the official QGIS download page at http://download.qgis.org. A huge thanks to the team at Lutra Consulting for taking this much-needed work, and to William Kyngesburye for the many years that he has contributed towards the macOS/OSX QGIS packaging effort!

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!

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.

Add Realistic Mist and Fog to Topography in QGIS 3.2

I recently came across a great tutorial by in which he demonstrated how to create map of Switzerland in the style of Edward Imhof, the famed Swiss cartographer renowned for his hand painted maps of Switzerland and other mountainous regions of the world. John’s map used traditional hillshading, multidirectional hillshading and crucially, a translucent topographic layer that created a mist like appearance he likened to the sfumato technique used by painters since the Renascence.

I followed John’s tutorial in QGIS 3.2 and I was quite pleased with the initial result below. However, the process creating it is a bit too complicated for a tutorial so I set about simplifying the process and rather than imitating Imhof’s distinct style, my goal this time is realism.

The heart of the effect involves the very clever idea of using the topographic layer as a subtle opacity mask to simulate mist, fog and atmospheric haze. Have a look at the image below taken on March 17th, 2005 by NASA’s Terra satellite. This is the industrialised Po valley of northern Italy, surrounded by the Alps and Apennine Mountains that rise above the valley’s hazy pollution. The haze adds a sense of depth to the surrounding hills and mountains. It’s not uncommon to see fog and pollution in satellite imagery that gives way to the clear air in high mountains e.g. northern India and Nepal, China, Pakistan and India. Creating a similar mist effect in QGIS is actually quite simple.

First download topography for the Alps and Po region (a 68.55 Mb GeoTiff file derived from freely available EU-DEM data I resampled from 25 to 100m resolution). Next, make sure you have the plugin QuickMapServics (QMS) installed (menu Plugins – Manage and Install Plugins). This great plugin provides access to over 1000 basemaps.

Load the GeoTiff file into QGIS (Raster – Load) and rename the layer Hillshade. Right click the layer to open the Layer Properties window. In the Symbology panel, next to Render Type, choose Hillshade. Change the altitude to 35 degrees, Azimuth to 300 degrees and Z Factor of 1.5 (illuminating the landscape from the top left). Finally, change the Blending mode to Multiply. Click OK to close the dialogue.

To add the basemap layer, Esri World Imagery (Clarity), type “ESRI clarity” in the QMS search bar to find and add the basemap; Go to View – Panels and activate the QMS search bar if it isn’t initially visible. Make sure it’s the bottommost layer.

Oh, that’s a bit disappointing, we only increased the relief little a bit. It’s missing the vitally important mist layer.

To create mist, right click the Hillshade layer and choose Duplicate. Rename the new layer Mist and make sure it’s above the Hillshade layer. Now open the Layer Properties window of the layer, we’re going edit it’s attributes to make it look like mist.

Change the Render type to Singleband Pseudocolor and use 0 and 3000 for the min and max values (limiting maximum latitude of the mist to 3000 meters). Then open the colour ramp window by clicking on the Color ramp and enter these values:

  • Left Gradient – HSV 215 15 50 and 75% transparency
  • Right Gradient – HSV 215 15 50 and 0% transparency

Close the Color Ramp dialogue. In the Layer Properties window, and this is very important, change the Blending mode to Lighten. Click OK to close the Layer Properties window.

Wow, we have mist!

The mist effect looks great. It certainly adds a lot of realism to the topographic map, it now looks quite like NASA’s images. This is just a quick and basic map so there’s lots of scope to improve the effect. Play around with the colour of the mist layer and its opacity, or even brighten the Hillshade layer underneath. See what effects these changes have.

Here’s another example below. In this example I duplicated the hillshade layer and set the second hillshade layer to Multidirectional Hillshading (yes, QGIS 3.2 has Multidirectional Hillshading). I then adjusted the transparency of both hillshade layers so they blended together nicely. I then replaced the basemap with another duplicated topography layer that I coloured using the gradient sd-a (by Jim Mossman, 2005) using the cpt-city plugin. And lastly, I doubled the opacity of the mist layer turning it into a milky fog. I think it looks great!

What next? Well, there’s lots of possibilities. Perhaps download Martian topography and add mist to the bottom of Valles Marineris?

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 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.

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 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.

Marco Bernasocchi (http://berna.io @mbernasocchi)

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.

Do you want to host a QGIS developer meeting?

Each year the QGIS.ORG community holds two developer meetings. These events are an important part of  our project – they provide an invaluable opportunity for us all to meet face to face and share ideas, discuss issues and plan the future of QGIS.

The host of the developer meeting gets a special bonus for hosting the meeting: One of our releases will be named after the town / village / city etc. where the event was held – like this:

We want to have a better idea of which venues we will be using for future events to help with out planning. So I am putting out a call for venue proposals:

If you would like to host a QGIS developer meeting (estimated 50 people per event) or a QGIS Conference (estimated 100-150 people per event) please contact us!

Please don’t submit proposals unless you have the authority to make such a proposal and are willing to act as the local organiser for the event. To make a proposal, fill out this form and tell us about your great venue!

 

Adding ESRI’s World Hillshade layer to QGIS

You may have seen my earlier tutorial where I described how to make nice looking hillshaded maps in QGIS using SRTM elevation data. Well, we don’t have to stop with just one hillshade layer on a map, it is possible to overlay multiple hillshades; a procedure that can increase the visual quality and detail. The following image is the hillshade we made before. Once you re-create a hillshade, following the previous tutorial, you can head to the next step (note that brightness and contrast settings may be different due to changes in how QGIS generates and displays hillshades).

We can improve the SRTM hillshade further by adding ESRI’s World Hillshade layer, which uses multi-directional illumination (also called a Swiss Hillshade in tribute to the celebrated Swiss cartographer Eduard Imhof). In addition, World Hillshade has a much higher resolution than SRTM 30m data in some regions of the world, it is 2m for most of the England and Wales, 10m for most of the US, 5m for Spain and 3m for Holland etc. The only drawback is that the style of this layer is somewhat controversial, some love it, some hate it, it looks like it’s illuminated from above, but mixing it with the SRTM hillshade obviates some of it criticised flaws.

To add the World Hillshade layer in QGIS go to the Layer Menu – Add Layer – Add ArcGIS MapServer Layer – click New and add the following URL:

https://services.arcgisonline.com/arcgis/rest/services/Elevation/World_Hillshade/MapServer

Notice QGIS 2.18 no longer needs a plugin to add ESRI layers, it new has this functionality built in. Also, open the url in a browser such as Firefox, it brings up a webpage that describes the layer. We also see links to other other layers. Yes, they can all be added to QGIS by simply taking the URL of the webpage that describe the layer and connecting to it via the ArcGIS MapServer Layer connector.

Name the layer World Hillshade and click Connect, then click and highlight the layer it connects to. Finally, click the Add button to add the layer to the canvas.

Next, we need to adjust the properties of the World Hillshade layer to properly overlay it above the SRTM hillshade layer. Make sure the World hillshade layer is the topmost layer. In the Layers Panel, right click Layer properties and in the window that opens up, click Style (if not visible). Next, change the Layer Blending mode (under color rendering) to Overlay. Adjust the layer’s brightness to around -20 and leave contrast at 0. If you find the scene is still too dark, brighten the SRTM Hillshade by increasing the layer’s brightness. You may also have to change (lower) the Min value of the Min – Max value boxes. Leave the contrast at 0 for the SRTM hillshade. Also, don’t brighten it too much as it might become washed out, loose detail, especially in bright areas. Play around the controls, settings may vary depending on the SRTM data you download and the version of QGIS you use.

Here’s a comparison in Ireland, a ring like structure of hills with a central peak. No, it’s not a meteorite crater. It’s a different kind of geological marvel, the Slieve Gullion Complex and its ring dyke; the deeply eroded remains of a 410 million year old Caledonian volcano. The SRTM hillshade is on the left and World Hillshade + SRTM hillshade is on the right (click on the image, it’s best appreciated full size):

We can see the World Hillshade + SRTM Hillshade layer shows much finer detail. We see a parallel array of roughly north-south orientated lines, these are fractures and faults that cut the Slieve Gullion Complex that were perhaps enhanced by glacial erosion. Also, look carefully, there seems to be some roads meandering across the landscape (hint, bottom of the map and right of the scale bar). You should get even better results with higher resolution World Hillshade data. We also notice that bending SRTM derived hillshade with World Hillshade adds a naturalistic illumination not apparent in multi-directional hillshading. So we have the best of both worlds, a high resolution hillshade and realistic looking illumination.

Hope you found this tutorial helpful.

QGIS Layout and Reporting Engine Campaign – a success!

Thanks to the tireless efforts and incredible generosity of the QGIS user community, our crowdfunded QGIS Layout and Reporting Engine campaign was a tremendous success! We’ve reached the funding goal for this project, and as a result QGIS 3.0 will include a more powerful print composer with a reworked code base. You can read more about what we have planned at the campaign page.

We’d like to take this opportunity to extend our heartfelt thanks to all the backers who have pledged to support this project:

We’ve also received numerous anonymous contributions in addition to these – please know that the QGIS community extends their gratitude for your contributions too! This campaign was also successful thanks to The Agency for Data Supply and Efficiency, Denmark, who stepped up and have funded an initial component of this project directly.

We’d also like to thank every member of the QGIS community who assisted with promoting this campaign and bringing it to the attention of these backers. Without your efforts we would not have been able to reach these backers and the campaign would not have been successful.

We’ll be posting more updates as this work progresses. Stay tuned…

 

2017 QGIS Governance Update

QGIS Developers and Community Members working on QGIS at our recent meet up in Essen, German,

Dear Voting members (and interested QGIS community members out there)

This is an open letter that was emailed to all QGIS voting members today

Just a quick note from me to thank you for participating in our ‘virtual AGM’ – I know it is a bit of an unusual system but it suits our geographically diverse nature well and we seem to have pretty good participation in the process (though I really encourage those voting members who did not participate to do so next time!).
I have done a bunch of updates on our governance section of the web site so you can find the AGM minutes, annual report, budget etc. all on the site, and I (or whoever is chair) will post them there in future years too so everything is in one place and easy to access. Here with the relevant links:
Since we have approved a new version of the statutes, I have replaced the old PSC page on the web site with the new charter:
Thank you all for the many useful hints, tips and suggestions I regularly receive on how to make things smoother within the project (keep them coming!) – hopefully we will get into a steady routine with this governance now. We have been going through a lot of ramp up trying to get templates, processes, etc in place as we switch over to QGIS.ORG legal entity etc. We appreciate your patience while we figure things out – and a very big thank you to Andreas Neumann and Anita Graser who have pitched in with a lot of administrative work behind the scenes to help get the QGIS legal entity in place!
What’s next? I will be starting the nomination process for 4 new community voting members, soon (one to match each of the incoming country user groups for Norway, Sweden, South Africa and France). At the end of that process we will have 31 voting members.
Soon QGIS.ORG will be in the Swiss Trade Registry, which means we can be VAT registered, can take ownership of the QGIS.ORG trademark (which is currently held in proxy for us) and of course present ourselves as a well governed project, hopefully attractive to large funders who recognize the global good a project like QGIS does!
