Abstract
Many factors condition extensive use of satellite images. This is due to the raw satellite imagery containing geometric distortions so significant that it cannot be directly superimposed to base maps. Other problems occur when remotely sensed data is merging into Geographic Information System (GIS). Recently, many authors have developed integration of Remote Sensing techniques and GIS to study hydrologic processes. Applications of integration of remotely sensed data with GIS for hydrologic studies concern the determination of land use, land cover classification, precipitation, soil moisture, evapotranspiration, water extend, ground water, water quality and runoff. In this paper a methodology to create a Digital Terrain Model (DTM),...I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
