Global GIS : World gazetteer (major cities)
- This datalayer is a point coverage representing major cities worldwide based on information from the GNS (GEOnet Names Server). For global (non-U.S.) cities, the GNS data was supplemented by the ESRI Data Maps (2000) World Cities layer. For United States cities, the GNS data was supplemented by data from the GNIS (Geographic Names Information System). This dataset was published as part of the USGS Global GIS : global coverage database (2003). The GEOnet Names Server provides access to the National Imagery and Mapping Agency's (NIMA) database of foreign geographic feature names. Approximately 20,000 of the database's 3.5 million features are updated monthly with names information approved by the U.S. Board on Geographic Names (US BGN). The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.
