摘要：Terrain relief modifications are mainly due to geodynamic processes, both internal and external earth processes, to climate change and to human activities. The dynamics of these processes can be shown as slow and progressive changes or as major relief modifications. Geomorphologic changes can be considered as slope geometry modifications. Thus the improvement in the monitoring of slopes provides a better knowledge of the geomorphologic change. In this work we propose the use of digital photogrammetry and the comparison of different dates photogrammetric flights in order to measure the change. Several flights from 1957 to 2003 over the Pas Valley (Cantabrian Range, Northern Spain) have been studied. A method to compare flights from different dates and features has been set up in order to explore the possibilities of monitoring the geomorphologic change through the analysis of digital terrain models (DTM).
