30 Second GLOBE Terrain

This data set was developed by National Geophysical Data Center, NESDIS, NOAA, and the U.S. Department of Commerce. The objective was to create the best available 30-arc-second global digital elevation data set based on data from existing data sets. The GLOBE terrain database contains data from 11 sources, and 17 combinations of source and lineage. It was developed during the 1990’s and was released in 1999. This is the same database that is found on the FCC web site for calculating domestic U.S. HAAT.
