description |
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 the U.S. Air Force, aimed at gathering spatial data for the creation of maps of vast remote areas for intelligence purposes. It was declassified in 1995. We used images taken on 24.09.1966. For this mission the KH-4M stereoscopic camera with 75% overlap was used. The KH-4A (Keyhole-4A) carried two J-1 (in earlier missions KH-3 cameras of 3.66 m resolution) panoramic cameras, with a focal length of 61 cm, and a ground resolution of 2.7 m to 7.6 m. The J-1 cameras were placed on an M (Mural) mount, one pointing 15° aft from the vertical and the other 15° forward. The minimal flight height was 180 km and the duration of each mission was 14-15 days. The panoramic cameras used work on the general principle that during the scanning process the lens and the scan arm moves while the film remains stationary. In this case the lens rotates around the second nodal point allowing the cylindrical focal plane to keep the image of distant objects sharp. As a result a 'bow-tie' shaped region is photographed and becomes ... |
