Data Sources. The following data sources were used to create GLOBEA. 1 DTED Level 0 discrete (spot) 30" DEM, sampled from the southwestern corner of the 30" GLOBE grid cell. 2 DTED-based 30" median DEM from USGS/GTOPO30. 3 DTED-based nearest-neighbor (to center of 30" GLOBE grid cell) DEM from USGS/GTOPO30. 4 DTED resampled to 30" by NIMA, provided to NGDC for public distribution in the 1980s. Spot (nearest-neighbor) version used. 5 DTED provided to USGS for public distribution in the 1970s, regridded to 30" by nearest-neighbor techniques by USGS. 6 DTED-based 30" “breakline” DEM from USGS/GTOPO30. 7 DTED-based DEM. Linear blending between classes 2 and 6 at their suture. 8 DEM for Australia. AUSLIG point elevation data base for Australia, converted to 30" DEM by NGDC (copyright 1998 by AUSLIG, licensed to NGDC for distribution with GLOBE). 9 DEM of Japan, from GSI. 10 DEM for Italy at high resolution from SGN, converted to 30" gridding by NGDC (for SGN). 11 DEM of New Zealand at 500m gridding by LCR, reprojected to 30" by USGS. 12 DEM of Greenland at 90" by NSIDC, converted to 30" by JPL. 13 Zwally (and others)/NSIDC/JPL and DCW blended DEM. Linear blending between classes 12 and 14 at their suture. 14 Digital Chart of the World. Developed by DMA from 1:1,000,000-scale maps, converted to 30" grid by USGS. 15 Maps for parts of southeast Asia and South America at 1:1,000,000 scale by AMS, digitized by GSI, gridded at 30" by USGS. 16 Maps for part of Brazil. Produced at 1:1,000,000 scale by the Fundacao Instituto Brasiliero de Geografia e Estatistica of Brazil as part of the International Map of the World series, adapted to digital vectors by GSI, gridded at 30" by USGS. 17 Map for part of Peru produced at 1:1,000,000 scale by the Ministerio de Guerra of Peru, adapted to digital vectors by GSI, gridded at 30" by USGS. 18 SCAR Antarctic Digital Database, converted to 30" DEM by USGS, subsequently repaired by NGDC.
