This dataset contains details of digital elevation models (DEM) and orthomosaic photographs (orthophotos) of seven 5 x 5 m erosion plots on Iron Tongue Hill, Tameside, Manchester. Plots were surveyed on ten occasions in 2018/2019 following a severe moorland wildfire (July 2018). Plots were surveyed using ground-based photogrammetry and Struture-from-Motion methods. The work was supported by the Natural Environment Research Council (Grant NE/S011560/1).

Provenance & quality

Using 40-60 ground based photographs per survey Structure-from-Motion (SfM) photgrammetric models have been created. A dense SfM point cloud was generated in Agisoft Photoscan (Metashape). Ground Control Point coordinates were used to scale and georeference the point clouds based upon the dGPS coordinates recorded in the field. The cleaned DEM dense point cloud and 1 mm/pixel resolution orthomosaic were exported as .tif files for later analysis.
