Locations of TB Lakes and Basins
This link is a downloadable GIS file (ESRI Shapefile) showing the geographic location of the TB lakes. There is also a KML file of the same data (i.e. KML file converted from the Shapefile) which can be displayed on Google Earth. The data was compiled from Surface Water Body Data (SWBD) source, which is available at: http://dds.cr.usgs.gov/srtm/version2_1/SWBD/ or http://earthexplorer.usgs.gov/
TB Lake Basins
This link is a downloadable GIS file (ESRI Shapefile) illustrating the drainage basins of the TB lakes. A KML file of the same data also is provided (i.e. KML file converted from the Shapefile) which can be displayed on Google Earth. A GIS-based procedure was used to generate the TB lake drainage basins, based on elevation data obtained primarily from the Shuttle Radar Topography Mission (SRTM) source ( http://earthexplorer.usgs.gov/) and Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) ( http://earthexplorer.usgs.gov/). The model delineated basin data has been validated to the maximum extent possible. Users should use their discretion when accessing the data for real-world decision making.
