Geo-referenced digital photographs with associated GPS waypoints and tracks for terrestrial ecosystem types from south-eastern Victoria Island, 2013
Geo-referenced digital photographs with the associated GPS waypoints and tracks of various terrestrial ecosystem types have been taken during the summer of 2013 in south-eastern Victoria Island, around Cambridge Bay, Nunavut. The photographs, in combination with additional GPS waypoints and tracks,...
