JGrassTools è una libreria di moduli di analisi territoriale basata sull'utilizzo di dati raster e vettoriali scritta in Java esviluppata da HydroloGIS, Dipartimento di Ingegneria Civile e Ambientale dell'Università di Trento e CUDAM. JGrassTools is a library of terrain analysis tools for raster and vector data The  library  is  written  in  Java  and  devel-oped  by  HydroloGIS,  the  Department  of Civil and Environmental Engineering of the University of Trento and the CUDAM. The objective of the project is on one hand to make it easier to a wide group of people to access existing data and models and on the other hand to make the implementa-tion of new models by scientists of differ-ent research centers easier. The   modules   currently   integrated   in JGrassTools  are  mainly  geomorphologic and  hydrologic  algorithms  for  the  evalu-ation of hydro-geologic risk and tools for the analysis of field data.
