As part of its data production workflows, the IGN (the French National Mapping Agency) has developped many QGIS plugins that can be of interest to the QGIS community and we have created QGIS Plugin to ease the access to services of the Geoplateforme

• Géoservices :

  • The GPF Isochrone–Isodistance–Routing plugin brings Géoplateforme’s mobility services into QGIS, offering fast isochrone, distance, and routing calculations. IGN supervised its development with Oslandia.
  • The French Locator Filter adds high‑quality French geocoding to QGIS using the Géoplateforme API. IGN funded the feature and coordinated the subcontracting with Oslandia.

• Data production tools : A first plugin, “Espace co,” has recently become available; its purpose is to allow users to populate specialized collaborative databases, such as BDTopo (the French national database). It is available here : https://plugins.qgis.org/plugins/ign_espace_collaboratif/

• Other plugins are currently under development, and we will strive to make them all available. A non-exhaustive list of what we plan to develop:

  • View plugin to have predefined styles based on data at your fingertips and to be able to share these styles among people working together.
  • Plugin for improved Z-axis management (visualization and correction) in QGIS
  • Plugin for managing lists of objects, saving them, and creating new ones…
  • Plugin for calculating the shortest path,
  • Plugin for digitization direction,

We are offering this presentation to explain our approach: why we chose to develop QGIS plugins and why we chose to make them available. We will present examples of use cases based on our own needs.

This presentation will allow us to gauge whether the QGIS community might be interested in these developments, potentially use them, and perhaps even contribute to them.
