GIS Lookup: Detailed Data Layer Listing

Data Layer GraphicTitle: "SRTM Water Bodies" (2006)
Description: SRTM Water Bodies (South West, one of six data sets) represents the lakes, rivers, and ocean areas within the SRTM coverage area (between 60 degrees North and 56 degrees South latitude) of the world. All SRTM elevation values within lakes and ocean areas were set to be a constant elevation for that feature. Elevation values within river areas were set to insure the proper flow direction. The primary source for these water features was a Landsat 5-based landcover water layer supplemented with medium-scale maps and charts. SRTM Water Bodies provides the geographic extent of where the original SRTM elevation values were altered to more accurately represent water surface areas within the data set. These data can also be used for cartographic display.
