Snow line altitude for A. P. Olsen Ice Cap

This dataset gives an average snow line altitude for the part of A. P. Olsen Ice Cap that falls within the hydrological catchment of Zackenberg River. The snow/ice boundary has been mapped manually from the Sentinel image from August that has no clouds and the highest snow line altitude. The snow line altitude is extracted at 100 m intervals at along the snow/ice boundaries from the same DEM (the Greenland DEM from the Danish Agency for Climate Data (https://dataforsyningen.dk/data/4780) which is a combination between ArcticDEMv3, GIMP og TREx.
