Abstract: The DEM data for 7.5-minute units correspond to the USGS 1:24,000 and
1:25,000 scale topographic quadrangle map series for all of the United
States and its territories. Each 7.5-minute DEM is based on 30- by
30-meter data spacing with the Universal Transverse Mercator (UTM)
projection. Each 7.5- by 7.5-minute block provides the same coverage as
the standard USGS 7.5-minute map series.
