# Mapping Mountain Landforms and Its Dynamics: Study Cases in Tropical Environments
## 6 Conclusions  
We presented a set of procedures for conducting geomorphological mapping in high mountain areas and the monitoring of the studied landforms, by combining field mapping and the use of GIS techniques. These areas are usually inaccessible for fieldwork, and the variety of the landforms is greater than in other areas. The proposed methodologies allowed the performance of better mapping of high mountain areas worldwide. We applied some of these procedures to develop a glacial geomorphology mapping of the highest summits of Costa Rica and Cerro Chirpio. In addition, we conducted a study and geomorphological mapping of a fluvial area of the Reserva Biologica Alberto Manuel Brenes, using UAV technologies. We agree with other authors that geomorphological maps are the baseline information for soil assessments, natural hazards mapping, and geoheritage evaluations, as well as for landscape and land-use planning. We also conclude that low-cost UAV surveying is a robust source of information for fluvial geomorphology analysis of reaches, especially in challenging environments such as humid tropical rainforests, where spaceborne and airborne sensors have great difficulty acquiring information regarding the river conditions. The UAV surveying and photogrammetric processing gives a clear example of how this type of technology can be deployed for geomorphological mapping of steep mountain river reaches.
