Web Services

A geOrchestra platform advertises standard web services to discover (CSW), view (WMS, WMTS), symbolize (SLD), query and download (WFS), edit (WFS-T), and even process (WPS) geographical features. It also provides powerful web applications making use of these services (and eventually combining them). It interoperates perfectly with GIS softwares such as QGIS and ArcGIS.


The project publishes one or two major releases per year (eg 23.0.0 or 23.1.0). They are supported for 12 months.

We also publish patch releases (eg 23.0.5) every month or so, to fix bugs and security issues.
