ESRI launch its new Geography Network, a collaborative system for publishing, sharing, and using digital geographic information on the Internet. "The Geography Network can be thought of as a large online library of distributed GIS information, available to everyone." Professional users can connect to the Geography Network and directly use the data and application services provided by other participants." Hundreds of data layers are currently available through the Geography Network. Worldwide offerings include political, elevation, vegetation, land use, socioeconomic statistics, and satellite imagery, to name a few. U.S. data includes administrative boundaries, detailed streets, topographic maps, natural hazards, environmental hazards, demographic statistics, crime statistics, and aerial photography.
