Use of terrestrial photographs for stereophotogrammetric modelling of glacier surface

A procedure for making close-up digital elevation models of glacier surface has been developed and the benefits of using these DEMs in glaciological change detection has been studied. The models can be used to follow accurately the changes of different surface features like melt water channels, glacier tables, ablation hollows etc. The results indicate that close-up DEMs can be used to densify more sparse DEMs and to detect changes in ice structure and movements.
