Geo-referenced digital photographs and videos with associated GPS waypoints and tracks for terrestrial ecosystem types on the northern shore of Greiner Lake, Cambridge Bay, Nunavut, 2015

Geo-referenced digital photographs and videos with the associated GPS waypoints and tracks of various terrestrial ecosystem types have been taken during the summer of 2015 on the northern shore of Greiner Lake, Cambridge Bay, Nunavut. The photographs and videos, in combination with additional GPS waypoints and tracks, characterize site, soil and vegetation characteristics of the arctic landscape. The geo-referenced photographs and videos, as well as the GPS data will be entered in a GIS software and overlaid on satellite imagery. By matching pixel colours of the satellite images with different ecosystem types in the field, a model will be developed that will allow the assessment of ecosystem types over large areas, based solely on satellite imagery. The digital photographs were taken on the ground with GPS-enabled cameras (geographical coordinates written in the image file's exif information). Digital videos of the landscape below were shot from helicopter. The geographical coordinates are stored in a separate text file associated with the video file. Additionally, waypoints and tracks associated with the photographs and videos were recorded with a handheld GPS device.
