Mapping environmental data with a Geographic Information System

Climate change is a current issue: temperature and rainfall raise, glaciers and snow melt and the global average sea level is rising. This cuases an increase of natural hazards (such as flooding risk and landslides), that could become more frequent. In this context, resident population should adapt to global environmental and climate change. The assessment of land use changes, occured since the last decades, can help controlling and understanding transformations. Nowdays, the Geographic Information System (GIS) technology is apllied to various sectors (environment, engineering, geology, architecture, etc.), in order to help stakeholdrs in analyzing different types of spatial data and to dispaly them in easy understandable maps. This study illustrates the land use changes of Muson river watershed (Treviso province, Northern Italy), occured in the last twenty years, and that contribute to conditioning the river hydrodynamic, in relation to climate change.
