Dataset Information

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.

opentopoID: OTDS.022019.32637.4
DOI: https://doi.org/10.5069/G9W0941H
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).
