Digital Elevation Model of Urji (west side of Corbetti volcano), Ethiopia

OT Dataspace
The raster DEM was generated from a point cloud, also uploaded to available from OpenTopography. This point cloud was generated from Pleiades stereo panchromatic optical images with 50 cm resolution. The data were processed using the Leica Photogrammetry Suite within ERDAS Imagine.
