Greenland Asiaq is a public enterprise under the Greenland Home Rule and the Department of Infrastructure and Environment.
Asiaq operates all over Greenland, undertaking activities concerning the physical environment. Our annual turnover is around 25 million DKK, 75 % of which is a grant from the Home Rule, while the remainder originates from commissioned assignments and external funding. We are presently about 32 employees, the majority of whom are natural scientists.
Asiaq’s responsibilities include; mapping, geographic information, hydrology, climate, environment, and surveying and geotechnical investigation. Our Workshop maintains a large network of climate stations throughout Greenland.
Asiaq collects relevant data from all over Greenland. Many of these data go back to the 1950s, meaning that Asiaq is responsible for both data collection and data storage. The grant from the Home Rule is used to collect, quality assure and store all the data on which we base our knowledge and advice. In addition, Asiaq offers to undertake related assignments for the Home Rule and other customers. Invoices are issued for these assignments.

Georeferenced aerial imagery at 2.5 meter per pixel resolution for much of the country is available from the governmental mapping agency LINZ under very liberal license terms (similar to BSD-with-attribution):
Two types are available: NZTM projection+NZGD2k datum (epsg:2193), and NZMG projection+NZGD49 datum (epsg:27200). The above website has GeoTiffs of the NZTM tiles, and claims the NZMG tiles are not georeferenced, but really they are, just not tagged with the metadata. Each of the NZMG tiles covers one NZMG 1:50k topo map (NZMS260 series), who's bounds can be found in a .csv file at the end of the NZMG orthophoto page. Armed with that info add the bounds and projection metadata to the NZMG Tiff download to make it into a GeoTiff using the gdal_translate utility from GDAL.
NZMG images are typically split into 4 parts, 20km x 15km ea. instead of the full 40x30km NZMG 1:50k topo sheet coverage. Those images seem to be grid registered, so remove 1/2 a cell inward around edges from the outer bound coordinate for cell bounds registered systems. (compensate as needed; I'm not sure if that is intended or due to an error in upstream processing)
- There are also 1:50k and 1:250k GeoTiffs of the modern NZTM topo maps available for download under similar libre-with-attribution terms:
