Development update Bridge for QGIS

Development update Bridge for QGIS

At GeoCat we are wrapping up our release candidate of the new Bridge plug-in for QGIS this week. We are grateful to all who installed the experimental plugin and provided feedback. This update is an opportunity to highlight some of the work the GeoCat Bridge team has been doing. Their goal was to improve both the technology and the product ahead of our release.

Highlights of QGIS plug-in

  • Fine-tuning cartography 

Developing a QGIS Plugin for GeoCat Bridge has been a great chance to take a look at the different rendering engines used by QGIS, GeoServer, MapServer and MapBox.GL.
These sorts of visual comparisons reveal differences in how styling is defined. The example above helped discover how many different ways QGIS has to represent transparency.
  • Navigating platform differences

The development work on the QGIS plug-in revealed a few differences that are not so easily addressed. Given an original map in QGIS Desktop, with rendering rules selected based on scale:
If we zoom to this same area with GeoServer, we end up with a different image!
Zooming closer we can see all the missing detail:
What is going on? This is a visual side-effect of QGIS and GeoServer working with different scale calculations:
  • QGIS is calculating scale based on measuring an approximate width of the current map.
  • GeoServer has a choice of scale methods, the default scaleMethod=ogc approach using a simplified scale calculation for interoperability, and scaleMethod=accurate taking into account the ellipsoidal shape of the earth.
We look forward to discussing these differences with the respective open source projects.

GeoCat Bridge QGIS plug-in availability

GeoCat Bridge provides a great one-click publishing story for Desktop GIS users. GeoCat Bridge publishes your geographic data, metadata and mapping to your choice of open source server platform. We are pleased to offer GeoCat Bridge to our customers as both an ArcMap extension and, shortly, as a QGIS plug-in. To obtain GeoCat Bridge please see our product page. A trial evaluation is also available.

Part of a vibrant Open Source community

GeoCat is pleased to be a member of the open source community. We would like to acknowledge everyone’s support with answering questions, reviewing pull-requests, and generally being amazing.

Release candidate of GeoCat Bridge for QGIS

Release candidate of GeoCat Bridge for QGIS

In the first quarter of 2020 we expect to present our new GeoCat Bridge for QGIS. This will be one of the most effective data publishing solutions for QGIS. The experimental plug-in is already available for download.

One-click publication workflow

GeoCat Bridge for QGIS provides a one-click publication workflow from desktop to web. GeoCat Bridge was previously known for helping ArcMap users publish data, metadata and importantly cartography to a GeoServer or MapServer stack. With GeoCat Bridge 4 we are pleased to bring this experience to QGIS Desktop.

First version of Bridge for QGIS

With great dedication our developers are working on our first version of Bridge for QGIS. At the FOSS4G conference in Bucharest in August we were proud to present a demo of Bridge for QGIS. In October we presented our release candidate at the QGIS Centric Meeting that was held on October 25th 2019 in Chattanooga (Tennessee, USA) at Chattanooga State Technical Community College.

Bridge for QGIS will be using QGIS layer identification information to register a published dataset in an online catalog. You can publish layers using GeoServer or MapServer; more options are being planned. Bridge for QGIS will have a great cartography support that adapts desktop styling to a wide range of formats. A new feature in the Bridge for QGIS (Bridge 4) are Mapbox vector tiles. Open Source Python Libraries are used to make it all happen.

Bridge for QGIS download

We expect to present the official version of Bridge 4 (for QGIS) in the first quarter of 2020. You then can buy GeoCat Bridge for QGIS (Bridge 4) and receive support or download the open source plug-in directly. The experimental plugin can already be downloaded at the QGIS.org-website or installed directly from the QGIS plug-in window.

GeoCat Bridge QGIS ArcGis

Bridge for ArcGIS Pro

In our roadmap of GeoCat Bridge 4 we have also included the development of GeoCat Bridge for ArcGIS Pro. We are still investigating whether or not to develop a Bridge 4 for ArcMap, as ESRI appears to have put its focus on Pro. If you’re interested in a Bridge 4 for ArcMap, please let us know. We will be running Bridge 3 and 4 in parallel.

Help us improve the GeoCat Bridge roadmap

We have set up a Bridge questionnaire to investigate which Bridge aspects users value and would like to see migrated or added to Bridge 4. We welcome you to fill out the questionnaire at https://forms.gle/31t8iv1xqoiMueQK9.
