Geoportal / Services & developers
Integrate Cameroon's geospatial data into your projects. The Geoportal exposes standard OGC services (WMS, WFS) usable in QGIS, ArcGIS, Leaflet, OpenLayers, or any compatible tool. No account required for public layers.
The Geoportal provides two types of services compliant with the Open Geospatial Consortium (OGC) standards. These services are compatible with all GIS software and mapping libraries on the market.
Map images
Returns pre-styled images (PNG, JPEG) of map layers, ready to display. Ideal for visualization and basemap display.
Service URL
Vector data
Returns geometries and published attributes in GeoJSON. Only the fields published by the producer are sent.
Service URL
The WMS service generates map images on the fly. Add the following parameters to the URL to get a map.
The WFS service returns geometries and published attributes, in GeoJSON only. Filter by extent (BBOX) or by spatial predicate; attribute filters, PROPERTYNAME and SORTBY are refused. Features per request are capped (100 anonymous, 1,000 signed in). For the full file, use the dataset download (sign-in required).
Before querying a service, identify the available layers. The Geoportal offers two methods to discover data.
Browse the catalog directly from the portal. Search by keyword, filter by theme, producer, or data type. Each record shows the available services and layer name to use.
Access the catalogQuery the service directly to get the full list of layers, their extents, coordinate systems, and available styles. This is the standard method used by GIS software.
The Geoportal services integrate natively into GIS software. Here are the steps for QGIS (the procedure is similar for ArcGIS).
Menu Layer > Data Source Manager, or Ctrl+L.
WMS/WMTS tab > New. Enter a name (e.g., Geoportal Cameroon) and paste the service URL.
Click Connect. The list of available layers appears. Select the ones you need.
Click Add. The layers appear on your QGIS map. For real features, use the GeoJSON address below or download the dataset: the standard QGIS WFS connection is not supported, because this service only answers in JSON.
Integrate the Geoportal services into your web applications, analysis scripts, or notebooks.

The services return data in several standard formats. Choose the one that matches your use case.
Image with transparency — ideal for overlay
Compressed image — ideal for basemaps
Standard web format — readable by all GIS tools and JS libraries
Native OGC format — maximum interoperability
ZIP archive containing .shp/.dbf/.shx — compatible with ArcGIS, QGIS
Table with coordinates — spreadsheet import, processing scripts
