A network consisting of six cameras was set up on both sides of Lange Glacier on King George Island, Antarctica, for a period of two years to monitor changes in the glacier's motion behaviour. The cameras were observing spatio-temporal glacier surface velocity vector fields as well as the position of the glacier front. Velocity field information was obtained from image sequences by applying subpixel accuracy photogrammetric image sequence analysis techniques. Georeferencing in a superordinate coordinate system was performed via integrated photogrammetric-geodetic network adjustment. As a result, velocity fields were determined with maximum glacier surface velocities in the order of 1.5 meter per day. The results of terrestrial camera image sequence processing can be used as validation and calibration reference for satellite image based glacier velocity dynamics calculations. Moreover, the very high temporal resolution of the image sequences taken at 20 minute time intervals can also be used to analyse highly dynamic processes.

| The work presented in this paper was supported by the Chilean INACH. The development of the basic techniques for glacier image sequence feature tracking was funded by the German Research Foundation (DFG). The software development was further supported by the program “support the best” of the Technische Universität Dresden. We would also like to thank the personnel of the INACH Base Profesor Julio Escudero and the Machu Picchu Antarctic Scientific Station of Peru for their support during the campaigns on King George Island. |
