These high resolution high-oblique time-lapse images were collected in hourly intervals from 5 locations around Helheim glacier in SE Greenland in the summer of 2013. Three cameras (Cameras 1, 2 and 3) were aimed at the calving front ~3.5 km down glacier from the calving front and two cameras (Cameras 4 and 5) were aimed cross-glacier ~3 km up glacier from the calving front. The images are in two stereo groups allowing the extraction of 3D data with significant processing though there are some optical issues that will degrade quality.

The database contains scanned photographs (at 1016dpi) of the UK and various locations around the world. Some are single band (black&white) others are 3 band colour. The images are stored in various formats on various types of magnetic media: .COT raw scans can only be used on the Intergraph ImageStation; .JPG (Intergraph format); .TIF. Processed scans may also be saved as stereomodels (with project data) and as orthophotographs. Mono coverage for most of the UK and we are constantly acquiring stereo data. Data is updated when unscanned areas are required by projects.
