Geospatial Open Data

Access

Public WMS/WFS/WMTS services and file downloads. No authentication.

Endpoints

• Service index: https://geoportaal.maaamet.ee/eng/services/public-wms-wfs-p346.html
• Base-map WMS capabilities: https://kaart.maaamet.ee/wms/alus?SERVICE=WMS&REQUEST=GetCapabilities
• Address/cadastral WMS: https://kaart.maaamet.ee/wms/aadressid?
• Orthophoto WMS: https://kaart.maaamet.ee/wms/fotokaart?
• ETAK WFS capabilities: https://gsavalik.envir.ee/geoserver/etak/ows?service=WFS&request=GetCapabilities
• Downloads: https://geoportaal.maaamet.ee/eng/spatial-data-p58.html

Retrieve

1. Fetch GetCapabilities for the selected service.
2. Read advertised layer/type names, supported CRS, operations, and output formats.
3. Use WMS GetMap for rendered imagery or WFS GetFeature for vectors; bound requests with BBOX, feature count, or filters.
4. Preserve the service URL, layer/type name, CRS, axis order, BBOX/filter, and output format.

Return

Keep authoritative layer identifiers, CRS, geometry type, source service, query parameters, feature attributes/geometries or map file, and retrieval time.

Limits

• Do not guess layer names from portal labels; use the current capabilities document.
• WMS is rendered imagery, not feature data.
• CRS axis order differs by WMS/WFS version; verify coordinates before spatial joins.

Verify

Require parseable OGC capabilities XML. WMS must expose a capabilities root and named layers; WFS must expose WFS_Capabilities, FeatureTypeList, and at least one feature type before issuing data requests.
