This data set consists of 1930s, 1960s and 1980s orto-mosiac of East Greenland in particular 260 km-long section of coastline between 66.3 and 68.4◦N The archival orthophotomaps were produced with the use of Agisoft Metashape (Agisoft Metashape, 2020). We used 3 data sets:a) British Arctic Air Route Expedition (BAARE), aerial oblique images taken between July 1930 and August 1931. Photogrammetric reconnaissance was done with the use of two De Havilland DH.60 Moth planes with Gipsy 1 engines equipped for taking vertical and oblique photographs with Williamson P14 camera with a lens of known focal length of 2209.8 mm (7.25'), and 127 mm ×101.6 mm (5' ×4') glass plates with envelope adaptors for changing slides in daylight were used. For our study we used 73 images obtained during the summers of 1930 and 1931. The data set was obtained from Scott Polar Institute and is licensed by this organization.b) CORONA satellite mission, 1959-72, mostly consists of satellite stereo pair images. It was lead by the CIA and ...
