GeoSUR Program Framework includes production of digital maps for South America using the digital elevation model of the Shuttle Radar Topography Mission (SRTM).
The SRTM is a joint initiative of the U.S. National Geospatial-Intelligence Agency (NGA) and NASA to produce topographic data for 80% of the landmass at a resolution of approximately 30 meters. These data are of limited distribution, the information available to the public has a resolution of 90 meters.
The U.S. Geological Survey (USGS) data obtained from SRTM 30 meters resolution will be processed for the area of South America under an agreement with the NGA, which stipulates that the source data may not be distributed, but the products by GeoSUR may be available to countries and the public.
Using the digital model the following derivatives could be produced: Shaded Relief, Slope, Aspect, Watersheds, Streamline, Flow Accumulation, Flow Direction, and intermediate products.
GeoSUR program will make these derived maps available on the Internet, and create a geoservice that will allow users to produce derived maps dynamically. This service will allow users to perform visualization analysis, generate shaded relief maps, or produce a profile between two selected points.
