More Detailed Maps of Greenland Coming Soon

The Arctic Journal reports on recent efforts to produce more detailed, systematic and accurate maps of Greenland.

Danish officials today announced promising initial results of a project using satellites to collect cartographic data faster and more efficiently than has been possible using aeroplanes.

The project involved using SPOT 6 and 7, two commercially operated European satellites, flying at an altitude of 700km to collect images of four specific areas […]. The pictures they returned over a two-year period beginning in 2015 each measure 360 square km. Objects as small as 1.5 m can be discerned in the pictures, making them detailed enough to be used to make precise, high-resolution maps.

Cartographers are now in the process of turning the data into finished, on-line maps. The maps themselves are expected to publicly available by autumn. But, even before that, the data gathered by the satellites will be placed on-line.
