James et al. (2020) - Mitigating systematic error in topographic models for geomorphic change detection: Accuracy, precision and considerations beyond off-nadir imagery

UAV-collected image dataset and associated image coordinates of GCP observations for surveys of la Borgne d'Arolla. See paper for details.

60m_10degr_3 : UAV image data

File formats for image observations:

.xml file contains GCP image observations (and other data) exported from Photoscan v1.4.2. Can be imported back into PhotoScan (or Metashape) using Import -> Markers.

.txt file contains GCP image observations as pixel coordinates given with respect to an origin in the top left image corner (tab-delimited text file). Note that the .txt file will contain a smaller number of observations than the .xml file, because only GCP observations that have been included in the bundle adjustment have been converted to .txt. The .xml files contain some additional unused observations (shown as grey furled flags in PhotoScan).
