The coastline of Kalaallit Nunaat/ Greenland available as a shapefile and geopackage, covering the main land and islands, with glacier fronts updated as of 2017
A coastline of Kalaallit Nunaat/ Greenland covering all land and islands, produced in 2017 for the BAS map 'Greenland and the European Arctic'. The dataset was produced by extracting the land mask from the Greenland BedMachine dataset and manually editing anomalous data. Some missing islands were added and glacier fronts were updated using 2017 satellite imagery. The dataset can be used for cartography, analysis and as a mask, amongst other uses. At very large scales, the data will appear angular due to the nature of being extracted from a raster with 150 m cell size, but the dataset should be suitable for use at most scales and can be edited by the user to exclude very small islands if required. The projection of the dataset is WGS 84 NSIDC Sea Ice Polar Stereographic North, EPSG 3413. The dataset does not promise to cover every island and coastlines were digitised using the data creator's interpretation of the landforms from the images.

Methodology:
Dataset compiled primarily from the ''IceBridge BedMachine Greenland, Version 3'': Morlighem, M. et al. 2017. IceBridge BedMachine Greenland, Version 3. Boulder, Colorado USA. NASA National Snow and Ice Data Center Distributed Active Archive Center. doi: https://doi.org/10.5067/2CIX82HUV88Y. Accessed 29/09/2017.
Using Esri ArcGIS 10.4, polygons were extracted from the 'land' mask with 'simplify polygons' selected, so as to slightly smooth the 150x150 m pixel size. Landsat 8 imagery was obtained for 2017 (courtesy of USGS) and the coastline was checked and manually updated against this imagery. Main changes included editing data that was incorrect or missing, and finally updating all major and most minor glacier fronts, where ice had retreated or advanced since the source date of the BedMachine dataset.
Data collection:
Data compiled using the following software: Esri ArcGIS v 10.4, QGIS 2.18.
Data quality:
We cannot comprehensively say that this dataset covers every island or is completely accurate for all sections of the coastline. It is possible to interpret satellite imagery in different ways, especially in snowy images or regions with sea-ice close to the coast, but the dataset was produced to the best available standard available with the creator's knowledge.
