Topographic Data and ImagesGridded Global TopographyThe Global Land One-kilometer Base Elevation (GLOBE) Project is a 30-arc-second (1-km) gridded, quality-controlled global Digital Elevation Model (DEM). Check the Gallery of GLOBE Images for some great map-like graphic arts from GLOBE. US State TopographyMap-like images for each US state of the United States have been developed using data from GLOBE. These show colored elevations, with shaded-relief details. Combined Topography & BathymetryGlobal Relief. NGDC's ETOPO1 supersedes the ETOPO2 2-minute gridded relief data set and TerrainBase and ETOPO5 which were produced at a 8 kilometer nominal grid (roughly five-minute resolution). ETOPO1 contains more detailed 1-minute gridded data. US Coastal Relief. NGDC's coastal relief digital elevation model combines 30-second topographic data with high-resolution bathymetry in US coastal regions. Tsunami Inundation Gridding Project. NGDC is developing high-resolution digital elevation models (DEMs) for select U.S. coastal regions in cooperation with NOAA's PMEL to be used in predictive tsunami research. |
