GeoCafe: Data Download

GeoCafe: Data Download

We offer the option to download some of the datasets produced by the GeoCafe project, in particular the Shuttle Radar Topography Mission (SRTM) data produced directly by EROS. For obtaining datasets produced by CATIE, IDIAF, CODOCAFE, ANACAFE, and ICAFE for the project please contact these agencies directly.

The SRTM is a joint project between the U.S. National Geospatial-Intelligence Agency (NGA) and NASA to produce topographic data for 80% of the Earth’s land surface. Elevation points at 1 arc seconds (approx. 30 meters) were produced. This data is of limited distribution, and the information is available to the public at 90-meter resolution. More information on http://www2.jpl.nasa.gov/srtm/

EROS obtained the 30-meter limited distribution SRTM data for Guatemala, Costa Rica, and the Dominican Republic. The agreement with NGA states that the source SRTM data won’t be released to partner countries, but that all derivative products will be. So far EROS has developed the following digital derivative products for these three countries:

  • Hill Shade
  • Slope
  • Aspect
  • Basins
  • Streamlines
  • Flow accumulation
  • Flow direction
