WPC is providing a subset of its product suite in KeyHole Markup Language (KML) format.   KML is used by a variety of GIS and mapping applications, including Google Earth, ArcGIS Explorer, Microsoft Virtual Earth, NASA WorldWind View, and numerous others, to display geospatial data on two-dimensional maps and three-dimensional Earth browsers.
