Comparison of methods for implementing high-resolution digital terrain models for reproducing the surface of glaciers.

The aim of the research is the tri-dimensional reconstruction of glacial topographic surfaces by the comparison of satellite images and traditional techniques, such as aerial photo images and topographic maps. The considered area La Mare Glacier (TN) East Alpes Italy, located in the Stelvio National Park, one of the Italian biggest national park. The double aim of the project is to validate and improve the techniques for the extraction of Digital Terrain Model (DTM) with a high morphologic complexity areas and to produce a DTM for studying, monitoring and quantifying the glacial resources. The DTM extracted from different sources will be integrated with GIS. Considering all the multi-disciplinary information that has been collected until now on this glacial areas, GIS represents the reference system for the analysis of the landscape changes.
