USGS generally relies on data from external sources to support its requirement for structures as a core layer in The National Map. The structures currently included at a national scope are hospitals, law enforcement, fire stations, and other similar essential facilities. This data was developed as part of an on-going effort between Federal agencies and States. For The National Map, the primary sources for the data are the States. In addition, the USGS reconciles the State data with the location and feature names from the Geographic Names Information System, achieving a single baseline of data for State and Federal vector data sources as well as gazetteer applications. By having a consistent baseline, all involved organizations can have a common view of the data content and also readily share data updates.
