The DT1 file type is primarily associated with 'DTED' by National Geospatial-Intelligence Agency. A data file of DTED (Digital Terrain Elevation Data) is a cell defined by latitudes and longitudes of a geographic reference system. The terrain elevation information is expressed in meters. The locations of elevation posts are defined by the intersections of rows and columns within a matrix. The required matrix intervals, defined in terms of geographic arc seconds, vary according to latitude. DT1 is generally 3 arcseconds.
