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).

本数据集为无人机（UAV）采集的影像数据集，附带用于拉博尔纳达罗廖（la Borgne d'Arolla）勘测的地面控制点（GCP, Ground Control Point）影像观测坐标，详细信息参见原论文。
60m_10degr_3：无人机影像数据
影像观测文件格式：.xml文件包含从Photoscan v1.4.2导出的地面控制点影像观测数据（及其他附属数据），可通过「导入→标记点」功能重新导入至PhotoScan（或Metashape）软件中。
.txt文件为以影像左上角为坐标原点的像素坐标形式的地面控制点影像观测数据（制表符分隔的文本文件）。需注意，.txt文件中的观测数据量少于.xml文件，这是因为仅纳入光束法平差的地面控制点观测数据才会被转换为.txt格式。.xml文件中还包含部分未使用的观测数据（在PhotoScan中显示为灰色折叠标记旗）。
