SLYR ESRI to QGIS compatibility suite – November 2019 update

It’s a been a month full of huge improvements since the last update, and we have some exciting news to share about our SLYR ESRI to QGIS compatibility suite. With the recently published plugin version 3.7, MXD conversion has moved from a “beta” state to being fully supported and available out-of-the-box for all users!

Based on our massive library of reference files (almost 10,000 files covering a huge range of ArcGIS versions and features!), the tool is now able to successfully convert 96% of LYR files and 94.5% of MXD documents. This is a significant milestone, and with it we decided that MXD conversion support is now stable enough to move out of its previous beta state.

Aside from this milestone, the 3.7 release brings many more enhancements and improvements, including:

  • SLYR now has full support for PMF published map documents created by ArcGIS Publisher, along with a new Processing algorithm to convert from a PMF document to a QGS projects
  • We’ve also added support for converting ArcScene SXD scenes to QGS projects. This conversion is 2-dimensional only for now, but we plan on adding 3D conversion when QGIS’ 3D support further matures.
  • We now convert all data frames contained within MXD documents, instead of just the first data frame. Currently, these are exposed as their own individual groups within the project layer tree (when we enable support for page layout conversion we’ll be automatically creating corresponding map themes from each data frame).
  • We’ve added support for reading many more layer types, including raster catalog layers, topology layers, terrain layers, and LAS dataset layers. While QGIS doesn’t have support for these layer types, we need to fully parse them in order to convert the rest of the MXD document contents. Whenever an unsupported layer type like these are encountered the plugin shows a warning advising users which layers could not be successfully converted.
  • We’ve also added support for reading TIN layers. Although previous QGIS versions had no means to read ESRI tin layers, thanks to work done in the MDAL library the upcoming QGIS 3.10.1 release adds full support for reading these data files! Accordingly, we’ll be unlocking support for converting TIN layers contained within MXD documents following the 3.10.1 release.
  • Full support for WMTS and tiled internet layers
  • Support for reading MXD documents which have repaired by the MXD Doctor utility
  • Support for layers with a geopackage source
  • Conversion of ImageServer based layers (since QGIS only has basic support for ESRI ImageServers, we convert these layers to their equivalent MapServer versions wherever possible)
  • Basic support for representation renderers. Although QGIS has no capability to utilise the symbology linked with a representation renderer, we’ve added support for rendering these layers using any geometry overrides which may be present for the features.
  • Conversion support for simple scale dependent renderers (these are a funny beast, which can’t be created directly through the ArcMap interface and which require custom ArcObjects code to create! That said, we’ve encountered a few examples of these inside our test library so have added support for converting them to the equivalent QGIS rule based renderer).
  • We added a new “random marker fill” symbol type to the upstream QGIS project, which will be available in QGIS 3.12 along with support in SLYR for conversion of ESRI random marker fills.

So what’s next for SLYR? Over the remainder of 2019 we’ll be working furiously toward 100% conversion rates for LYR and MXD files. We’ll also start rolling out conversion support for page layouts to QGIS print layouts, and support for automatic conversion of ArcMap TIN layers to QGIS mesh layers.

Keep an eye on this blog and our Twitter channel for further updates!

 

SLYR ESRI to QGIS compatibility suite – October 2019 update

Recently, staff at North Road have been hard at work on our SLYR “ESRI to QGIS compatiblity suite“, and we thought it’s time to share some of the latest exciting updates with you.

While SLYR begun life as a simple “LYR to QGIS conversion tool”, it quickly matured into a full ArcGIS compatibility suite for QGIS. Aside from its original task of converting ESRI LYR files, SLYR now extends the QGIS interface and adds seamless support for working with all kinds of ArcGIS projects and data files. It’s rapidly becoming a must-have tool for any organisation which uses a mix of ESRI and open source tools, or for any organisation exploring a transition away from ArcGIS to QGIS.

Accordingly, we thought it’s well past time we posted an update detailing the latest functionality and support we’ve added to SLYR over the past couple of months! Let’s dive in…

  • Full support for raster LYR file conversion, including unique value renderers, color map renderers, classified renderers, RGB renderers and stretched color ramp renderers:

    From ArcMap…

    …to QGIS!
  • Support for conversion of fill symbol outlines with complex offsets, decorations and dashed line templates
  • Conversion of 3D marker and simple 3D lines to their 2d equivalent, matching ArcMap’s 2D rendering of these symbol types
  • Beta support for converting map annotations and drawings, including custom text labels and reference scale support
  • Label and annotation callout support*
  • Support for converting bookmarks stored in MXD documents*
  • Support for converting ESRI bookmark “.dat” files via drag and drop to QGIS*
  • Correct conversion of OpenStreetMap and bing maps basemap layers
  • SLYR now presents users with a friendly summary of warnings generated during the LYR or MXD conversion process (e.g. due to settings which can’t be matched in QGIS)
  • Added support for MXD documents generated in very early ArcMap versions
  • We’ve added QGIS Processing algorithms allowing for bulk LYR to QLR and MXD to QGS conversion. Now you can run a batch conversion process of ALL MXD/LYR files held at your organisation in one go!
  • Greatly improved matching of converted symbols to their original ArcGIS appearance, including more support for undocumented ArcGIS symbol rendering behavior
  • Support for conversion of text symbols and label settings stored in .style databases*
  • Directly drag and drop layers and layer groups from ArcMap to QGIS to add them to the current QGIS project (maintaining their ArcGIS symbology and layer settings!)*
  • Directly drag and drop layers from ArcCatalog to QGIS windows to open in QGIS*
  • Support for ESRI MapServer layers

(*requires QGIS 3.10 or later)

Over the remainder of 2019, we’ll be hard at work further improving SLYR’s support for MXD document conversion, and adding support for automatic conversion of ArcMap print layouts to QGIS print layouts.

While SLYR is not currently an open-source tool, we believe strongly in the power of open source software, and accordingly we’ve been using a significant portion of the funds generated from SLYR sales to extend the core QGIS application itself. This has directly resulted in many exciting improvements to QGIS, which will become widely available in the upcoming QGIS 3.10 release. Some of the features directly funded by SLYR sales include:

  • A “Segment Center” placement mode for marker line symbols
  • Reworked bookmark handling in QGIS, with a greatly enhanced workflow and usability, and a stable API for 3rd party plugins and scripts to hook into
  • Improved handling of layer symbology for layers with broken paths
  • Auto repair of all other broken layers with a matching data source whenever a single layer path is fixed in a project
  • Support for managing text formats and label settings in QGIS style libraries, allowing storage and management of label and text format presets
  • A new Processing algorithm “Combine Style Databases“, allowing multiple QGIS style databases to be merged to one
  • Adding a “Save layer styles into GeoPackage” option for the “Package Layers” algorithm
  • New expression functions which return file info, such as file paths and base file names
  • Adding new options to autofill the batch Processing dialog, including adding input files using recursive filter based file searches
  • Coming in QGIS 3.12: A new option to set the color to use when rendering nodata pixels in raster layers
  • Coming in QGIS 3.12: A new “random marker fill” symbol layer type, which fills polygons by placing point markers in random locations

Announcing our SLYR (MXD to QGIS) funding drive!

One product which North Road had the chance to develop last year, and which we are super-proud of, is our SLYR ESRI style to QGIS conversion tool. If you haven’t heard of it before, this tool allows automatic conversion of ESRI .style database files to their equivalent QGIS symbology equivalent. It works well for the most part, and now we’re keen to take this to the next stage.

The good news is that North Road have been conducting extensive research and development over the past 12 months, and we’re pleased to announce our plans for extending SLYR to support ESRI LYR and MXD documents. The LYR and MXD formats are proprietary ESRI-only formats, with no public specifications allowing their use. This is a huge issue for organisations who want to move from an ESRI environment to the open geospatial world, yet are held back by hundreds (or thousands!) of existing ESRI MXD map documents and layer styles which they currently cannot utilise outside of the ESRI software ecosystem. Furthermore, many providers of spatial data only include ESRI specific layer formatting files with their data supplies. This leaves users with no means of utilising these official, pre-defined styles in non-ESRI tools.

In order for us to continue development of the SLYR tool and unlock use of LYR and MXD formats outside of ESRI tools, we are conducting a funding campaign. Sponsors of the campaign will receive access to the tools as they are developed and gain access to official support channels covering their use. At the conclusion of this drive we’ll be releasing all the tools and specifications under a free, open-source license.

You can read the full details of the campaign here, including pricing to become a project sponsor and gain access to the tools as they develop. As a campaign launch promo, we’re offering the first 10 sponsors a super-special discounted rate (as a reward for jumping on the development early).

The mockup below shows what the end goal is: seamless, fully integrated, automatic conversion of MXD and LYR files directly within the QGIS desktop application!

Converting MXD to QGIS Project File

On Wednesday, Allan Maungu – geoscripting.blogspot.com announced MXD2QGS, a converter that exports layers from an Arcmap 10 document into a Quantum GIS project file. The tool is built as an ArcToolbox and can be downloaded from the blog.

I’d be very interested to hear whether this tool works for you.
