Dynamic GIS and Remote Sensing for the diagnosis and geological monitoring of catchment areas

This work aims to propose an articulate project about specific exigencies of territorial civil engineering, particularly about a GIS on diagnosis and monitoring of the geological and envi-ronmental order of a geographic basin, integrated with remotely sensed data. This work shows an application of dynamic GIS useful for monitoring, control and anticipating of landslides and min-ing areas. The architecture of this GIS is realized with reticular technical maps and remote sensing data. In this project we analized a small area in the southern part of the "Calabrian Arc." Everyone knows how difficult is modeling of a landslide and monitoring of the subsurface because of the variety of numerous factors involved. For this purpose is suitable the creation of a dynamic GIS decision support where the input data are geo-referenced spatial information (geographical data and descriptive attributes) and output is the result of space-time processing and / or logical on these data. More specifically, on the ground monitoring stations, global satellite positioning systems and Landsat, Spot imagery (with different spatial and radiometric resolution) provide useful information to the central system (GIS) that processes the information and provides output to users both in the laboratory as in situ. Special relevance for the purpose of processing have the various models produced to create the logical connections between the individual thematic maps (if necessary realized) and to interpret and explain the data in the phenomenological or physical context of the system land. The processing models used are algorithms for union and intersection data and multidimensional statistical algorithms.
