- catalog abstract "Data downloaded from USGS in BIL format, and translated into ESRI Grid format. GTOPO30 is a global digital elevation model (DEM) that covers the globe and has a horizontal grid spacing of 1 km (30-arc second) resolution. It is 16-bit signed integer data in simple binary raster format. GTOPO30 was derived from several raster and vector sources of topographic information. It was developed between 1993 and 1996 through a collaborative effort led by staff at the U.S. Geological Survey's EROS Data Center (EDC).".
