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 Tsijiore Nouve.<br>Notes:GCP ground survey data were acquired through two dGPS surveys. The values provided are the precision-weighted mean coordinates (each point was measured once in each survey). Excluding GCP 1, point coordinate measurement differences between the two surveys had means of 3.1, -10.3 and 1.5 mm in Easting, Northing and altitude respectively and associated standard deviations of 11.1, 22.0 and 31.6 mm.GCP 1 was determined to be located on unstable ground and is not recommended for use in photogrammetric processing.<br>See paper for further details.
