Digital terrain models (DTM) for the modeling of natural disasters in high alpine regions:
Digital terrain models (DTM) for the modeling of natural disasters such as avalanches or glacier lake outburst are one of the main input data. But specially in high alpine regions such as the Pamirs in Tajikistan the availability of accurate DTM is very limited. The use of space-borne acquired DTM is the only way to overcome these shortcomings.
The freely available DTM derived from the optical data of the Advanced Thermal Emission And Reflection Radiometer (ASTER) instrument on TERRA satellite and the Shuttle RADAR Topography Mission (SRTM) could fill this gap. But both DTM have many disadvantages.
The project was addressing the combination of both DTM to combine the strength of the individual DTM and to provide a reliable DTM in high mountainous regions.
