| contents | Google Earth KMZ files from a study of endorheic basins using the GIS program Global Mapper in combination with shapefiles from the HydroBASINS dataset (Lehner & Grill, 2013). The study created continental-scale models (DEM-derived basins, or DDNs) of the connections between endorheic and exorheic basins. The DDNs for endorheic basins associated with exorheic basins larger than 25,000 sq km are here presented in Google Earth KMZ format. The files are very large, so are broken down by continent, and in the case of Asia, by sub-continent. Geospatial features within the KMZ files include the following: Polygons: (a) Every endorheic basin in the HydroBASINS dataset; (b) Every exorheic HydroBASIN basin > 25,000 sq km through which endorheic streamflow lines reached the ocean; (c) Closed contour areas marking endorheic area depressions and potential palaeolakes. Lines: (a) Streamlines from the lowest elevation point of every endorheic basin, classified by whether or not they drained into an exorheic basin >25,000 sq km; (b) Streamlines extracted from the HydroSHEDS 30-second river network shapefile, which represent the actual drainage lines of all the exorheic basins > 25,000 sq km. Points: (a) The lowest elevation point in every endorheic basin from which streamflow was initiated in Global Mapper's Generate Watershed process; (b) Every intersection between endorheic streamflow lines and the boundary of the exorheic basin within a DDN, for investigation as possible wind gaps between exorheic and endorheic basin;. (c) The outlet to the ocean of a DDN, when the location of that outlet varied significantly more than 4 km from the outlet of the HydroSHEDS river network, for investigation as possible palaeo-distributary channels. |
