Atlas of the Cryosphere Web Feature Service (WFS) now available

Release Date: February 7, 2007

Select vector data sources (i.e. points, lines, and polygons) for the Atlas of the Cryosphere ( are now accessible remotely via the Open Geospatial Consortium (OGC) Web Feature Service (WFS). While the OGC Web Map Service (WMS) provides map images of these and other Atlas layers, WFS provides the actual source data, encoded in Geography Markup Language (GML) format. In the near future, the Atlas will also support the Web Coverage Service (WCS) for accessing select raster data sources (stay tuned to this RSS feed for an announcement later this month). For more details about accessing Atlas of the Cryosphere OGC services, click here. These international specifications provide a framework for sharing maps and geospatial data over the internet.
