Datasets Available as OGC Mapping Services

DGS offers many of our data products as web services in WMS (Web Map Server) and WFS (Web Feature Service) format. WMS and WFS are standardized, open protocols for requesting geospatial data over the web. (Read about the specifications for WMS and WFS services.) WMS services can be read in any web browser or directly in most GIS packages, such as ArcGIS and Quantum GIS. WFS services are typically more restricted to GIS software as they offer more flexibility to manipulate the data.

For all OGC services served by DGS:

  • All WMS services support GetMap, GetCapabilities, and GetFeatureInfo requests. WFS suports the GetFeature request. They do not provide SLD support.
  • Available image formats are jpeg and png
  • Coordinate systems are EPSG:4326 (native), EPSG:4269, EPSG:26957, EPSG:4152, EPSG:2776, EPSG:3857, EPSG:900913
