The primary goal of the U.S. Geological Survey's (USGS) elevation data program is to ensure public domain availability of elevation data for the nation. These data describe the topography of the land surface and can be used in numerous applications both as standalone products or in combination with other types of geospatial data, such as digital line graphs (DLG's) and digital orthophoto quadrangles (DOQ's). Data availability will be achieved through the development of production and cooperative partnerships with all levels of government, academia, and private industry.
Some goals of the program include completion of national coverage of the 2-arc-second (30-minute) digital elevation models (DEM's), development of an elevation data maintenance strategy, continued support of the digital orthophoto program, and continued support of the National Spatial Data Infrastructure's (NSDI) elevation framework requirements.
Long term goals include developing a geographic (arc-second) seamless elevation data base from which multiple resolutions of data can be derived, continuing to identify and support multiple producers and sources of elevation data, and continuing to work with the Federal Geographic Data Committee (FGDC) in developing and supporting inclusive standards for multiresolution data.
