QGIS contributions by Oslandia

Oslandia has been contributing to the opensource GIS community in general, and QGIS in particular for many years, at various levels :

• we are involved in the QGIS community and have multiple “community voting members” in our team
• we are a committed actor of France’s QGIS User Group (and OSGeo-FR)
• we are OGC member and OGC French forum member
• we are involved in the Francophone OSGeo local chapter
• we support and participate to community events (FOSS4G, FOSS4G-fr, “rencontres QGIS”, PgDay…)

We contributed numerous improvement and features in QGIS. Here are a few links to some features we implemented.

• Virtual layers
• DB Manager improvements
• The ATLAS feature
• Attribute table improvement : copy-pasting
• Inverted polygon renderer
• Arrow symbol layer
• CAD tools

• Better charts management

• QGIS Server multithreading
• Map magnifier tool
• Filter legend by expression
• Form constraints
• Auxiliary storage – QGZ

• Refreshing maps from postgreSQL
• Custom labelling

Oslandia implemented a continuous integration server dedicated to :

• OGC compliancy tests for WMS 1.3.0 et WFS 1.1.0
• QGIS server performance tests (example)

QGIS.ORG mandated Oslandia to administer this server.

Our hard work on QGIS Server lead to OGC certification as a reference implementation for WMS 1.3.0.

We also implement plugins, generic or tailored to our client’s needs :

• qgis-versioning
• qgis-epanet
• WAsP
• Menu Builder
• GML toolbox
• Mask
• etc.
