 1. USGS 30 ARC-second Global Elevation Data, GTOPO30 (ds758.0)

GTOPO30 is a global raster digital elevation model (DEM) providing terrain elevation data with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer). GTOPO30 was derived from ...  several raster and vector sources of topographic information. For easier distribution, GTOPO30 has been divided into tiles. Detailed information on the characteristics of GTOPO30 including the data distribution format, the data sources, production methods, accuracy, and hints for users, is found in the GTOPO30 README file.

GTOPO30, completed in late 1996, was developed over a three year period through a collaborative effort led by staff at the U.S. Geological Survey's EROS Data Center (EDC). More information is available through the EDC website.

 2. USGS Land Use and Land Cover, 200m (ds762.0)

200 m resolution Grids of Land Use and Land Cover for selected US locations prepared by the USGS

 3. USGS Selected 3-Second Elevations for Colorado, Hawaii, and the U.S. Great Plains (ds756.5)

This dataset contains 3-second terrain elevation data, from the U.S. Geological Survey, for Colorado, Hawaii, and the U.S. Great Plains covered by the Storm Fest project.

 4. South African Area 1-Minute Elevation Data (ds761.0)

This dataset contains gridded 1-minute resolution terrain elevation data for the area around South Africa.

 5. Staub and Rosenweig's GISS Soil and Surface Slope, 1-Degree (ds770.0)

Global data for soil type, texture, surface slope and other properties, at a 1 degree resolution. Based on FAO soil maps (1974) and on Matthews vegetation dataset (DS765.0.). Has ...  more details about soil than the Wilson dataset (DS767.0) (from Zobler, 1986 files). See NASA TM 100685, Stauband Rosenzweig.

 6. Argonne 0.2-Degree Land Use and Deposition Data (ds766.0)

This dataset contains land use classification data on a 1/6-degree by 1/4-degree grid covering the United States from 52W longitude to 134W and from 24N latitude to 54N. Also  ...  included is a dry deposition model that uses the land use classification (and other user-supplied meteorological parameters) to compute the deposition velocities of sulfur dioxide (SO2) and sulfate (SO4) pollutants.

 7. Defense Mapping Agency (DMA) U.S. 30-Second Elevations (ds756.1)

This dataset contains elevations at every 30 seconds of latitude and longitude for the region from 23N to 51N and 130W to 60W (the contiguous United States). These data ...  are current as of August, 1989.

 8. U.S. Navy 10-Minute Global Elevation and Geographic Characteristics (ds754.0)

This free dataset, compiled by the U.S. Navy Fleet Numerical Oceanography Center (with data help from NCAR), contains global elevation data at 10-minute resolution. Each 10-minute x 10-minute ...  area contains modal, maximum and minimum elevations, orientation of ridges, terrain characteristics, and urban development. These data are current as of December 1984.

 9. U.S.A.F. Global 1-Degree and 5-Minute Average Elevation Data (ds755.0)

This free dataset contains average elevation data at 1-degree resolution for the globe, and at 5-minute resolution for Europe, parts of North Africa, and most of ...  North America.

 10. NMC Global Elevation Data, 2.5-Degree and Spectral (ds757.0)

This dataset contains global terrain elevation data on a 2.5-degree latitude/longitude grid and spectral coefficients of terrain that can be used to create terrain fields for any truncation.
