A 10 m land mask for the Nuup Kangerlua, Kobbefjord, and Ameralik fjord systems in southwest Greenland

This dataset consists of a 10 m land mask of the Nuup Kangerlua, Kobbefjord, and Ameralik fjord systems in southwest Greenland. The land mask is based on two Sentinel-2 MSI images of the area (tiles WDS and WES) that were acquired at high tide on 30 July 2017. Land was masked by applying a threshold of 0.1 Wm-2 to the short-wave infrared (SWIR) band at 1614 nm. Mountain lakes and shaded coastal regions were masked using the TanDEM-X digital elevation model. Some inland waters were masked manually. 

Land and water were assigned values of 0 and 1, respectively, and are provided in geotiff format projected to UTM Zone 22 (WGS 84).

The boundaries of the mask area extend from 63.90°N, 51.999°W in the southwest to 64.01°N, 51.302°W in the northeast.
