Assessing the global land one-km base elsevation DEM

The Global Land One-kilometer Base Elevation (GLOBE) digital elevation model is the most thoroughly designed, reviewed, and documented global digital elevation dataset to date. Developed by an international group of specialists, GLOBE comprises a global 30 arc-second latitude-longitude array, with land areas populated with integer elevation data. GLOBE is available on the World Wide Web, and on CD-ROM in a format convenient for image processing and raster geographic information systems (GIS). Full GLOBE documentation accompanies the CD-ROM and appears on the Website (http://www.ngdc.noaa.gov/seg/topo/globe.html). This paper summarizes some findings made during GLOBE’s development.
