DETERMINATION OF SPATIO-TEMPORAL VELOCITY FIELDS ON GLACIERS IN WEST-GREENLAND BY TERRESTRIAL IMAGE SEQUENCE ANALYSIS
Some glaciers in Greenland are currently showing dramatic changes: A fast retreat of the glacier front, thinning and acceleration of glacier movement. As a prominent example, Jacobshavn Isbræ glacier has accelerated from 20 meters per day to 40 meters per day within a few years. These effects can ve...

Some glaciers in Greenland are currently showing dramatic changes: A fast retreat of the glacier front, thinning and acceleration of glacier movement. As a prominent example, Jacobshavn Isbræ glacier has accelerated from 20 meters per day to 40 meters per day within a few years. These effects can very well be observed by photogrammetric and remote sensing techniques. In the paper, we report on recent measurements at three glaciers in West Greenland: Jacobshavn Isbræ, Eqip Sermia and Støre Qarajaq. The paper will concentrate on the determination of spatio-temporal velocity fields from high resolution terrestrial image sequences captured by a 39-Megapixel camera. In addition, the glacier front retreat has been mapped from multi-temporal satellite images, and a terrestrial laserscanner has been used to determine glacier surface models and glacier motion from multiple scans. The results of the photogrammetric measurements form a valuable basis for glaciological research on the changing behavior of glaciers. 1. |
