Structures

The structures data theme consists of name, function, location, and other characteristics of selected manmade facilities. Types of structures collected are largely determined by the needs of disaster planning and emergency response organizations. Structures data are designed to be used in general mapping and in the analysis of structure related activities using geographic information system (GIS) technology. In mapping, structures are used with other data themes, such as elevation, boundaries, and transportation, to produce general reference maps. These maps often serve as base maps for special purpose mapping. Structures data can be accessed and downloaded at: http://viewer.nationalmap.gov/.
