Spatial Data Services

SEDAC Mapping Services

Web Map Service (WMS) and Web Feature Service (WFS) layers are available from SEDAC servers directly using any WMS or WFS compliant client. Services for vector data respond to both WFS (data) and WMS (map) requests. The tables below list the services available and provide links to the GetCapabilities documents that are required to access the services from an OGC-compliant client.

Population data from Gridded Population of the World (GPWv3) are available via the Web Coverage Server (WCS) specification on a test (beta) WCS server. When testing is complete, selected raster WMS services will also be made available as WCS layers for service-based access.
