Untraditional topographic mapping in central West Greenland

Abstract

During the geological investigations carried out in central West Greenland (see Schiener, this report) a cartographical programme was carried out to test a newly developed method of producing topographic maps direct from aerial photographs. The programme was adapted to the working conditions of the geologists and the author was attached to different geological parties working on western and central Nugssuaq, southern Disko, Hareøen and Ubekendt Ejland. Within the two months' season sufficient measurements were obtained to enable eventual topographic map coverage of 1700 km² with acceptable accuracy for geological mapping at the scale 1:50 000.
