Universidad glacier surface drainage map, ...

The shapefile contain vector data with lines representing the drainage network on the surface of the tongue of the Universidad glacier. The lines were obtained with use of PCRaster plugin in the Quantum GIS 3.28 program (Karssenberg et al. 2010). The plugin relies on Strahler method to trace the streams on a digital elevation model. Fields: arcid - ID of the feature; grid_code: Strahler order of the stream.
