Digital Elevation Model of Gedemsa volcano, Ethiopia

OT Dataspace
The point cloud and raster DEM were generated from Pleiades stereo panchromatic optical images with 50 cm resolution. The data were processed using the Leica Photogrammetry Suite within ERDAS Imagine.

opentopoID: OTDS.022019.32637.2
DOI: 10.5069/G94J0C6X
Platform: Structure from Motion / Photogrammetry
Data Format: Point Cloud, Raster
Dataset Acknowledgement: Funding for Pleiades imagery was provided by a grant from COMET (NERC Centre for the Observation and Modelling of Earthquakes, Volcanoes, and Tectonics). Processing work was supported by a studentship from NERC as part of the Environmental Research DTP (University of Oxford).
