Monitoring glacier elevation and volume changes with digital photogrammetry and GIS at Gepatschferner glacier, Austria

International Journal of Remote Sensing, 2006
Digital elevation models of Gepatschferner in Northern Tyrol, Austria were obtained with digital photogrammetry from high altitude stereo photo pairs and by digitizing an analogue topographic glacier map, for 1990 and 1971, respectively. A difference map was calculated to identify regions of glacier elevation increases and decreases corresponding to ...

Quantification of glacier volume change using topographic and ASTER DEMs

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
Satellite imagery has been largely used to measure glacier surface evolution by detecting surface change between two images taken at different dates. But until now it seemed difficult to evaluate glacier volume changes from space. In this study, volume changes of three small glaciers in the Cordillera Blanca (northern Peru) between 1962 and 2001 are ...

Volume Change of the Tasman Glacier Using Remote Sensing

2008
Mountain glaciers are expected to be the greatest contributor to sea level rise over the next century. Glaciers provide a good indicator of global climate and how to monitor their change is an increasingly important issue for climate science and for sea level rise forecasts.

A global machine learning system for glacier ice volumes

Knowledge of glacier ice volumes is crucial for constraining future sea level potential, evaluating freshwater resources, and assessing impacts on societies, from regional to global. Motivated by the disparity in existing ice volume estimates, we developed a global machine learning framework to model the ice thickness of individual glaciers.
