James et al. (2020) - Mitigating systematic error in topographic models for geomorphic change detection: Accuracy, precision and considerations beyond off-nadir imagery<br>GCP coordinates in Swiss Grid CH1903/LV03 (EPSG::21781) for associated UAV surveys of la Borgne d'Arolla.<br>Notes:GCP ground survey data acquired by total station. Precision values are relative estimates (i.e. within the network) rather than absolute georeferencing, and were computed from least-squares network adjustment of data acquired from three stations. Absolute georeferencing was achieved using three dGPS-surveyed station positions; absolute georeferencing precision was not comuputed, but is not expected to be substantially worse.GCP 4 was covered by sediment prior to image capture, so not used in the photogrammetric processing.<br>See paper for further details.
