To access an OpenCatalog, the supported browsers are :
- Mozilla Firefox 82 and + ;
- Google Chrome 86 and + ;

In SaaS mode, a minimum download speed of 500 Kb/s is required to access OpenCatalog.
Supported geographic services¶
OpenCatalog lets you use map service layers to visualize and extract data. The following services can be used:
- feature services from an OGC, WFS or Esri service, with Esri Feature Service authorizing data extraction in json/geojson or GML3 format,
- map services from an OGC service, WMS, or Esri, Esri Map Service,
- tiled services from an OGC service, WMTS, or an Esri service, Esri Tile Service.
By default, the services in question must be public and open in order to be accessible from OpenCatalog. However, no-proxy mode allows access to view and retrieve services accessible on the organization's internal network if they are not subject to authentication.
On premises
In On-premises mode, services must be accessible on the machine hosting Opencatalog.
Layer groups are not currently taken into account; only layers can be used.
