PCRaster is a powerful package of software for map algebra and environmental dynamic modelling. The main applications of PCRaster are found in environmental modelling. In the PCRaster package a rich suite of geomorphological and hydrological functions is available. These include functions for visibility analysis, catchment analysis and routing of transport (drainage) of material in a catchment using interactively generated local drain direction maps and transport (routing) operations. These operations are made available in the QGIS Processing Toolbox through the PCRaster Tools plugin. This presentation will show applications, the current state of the plugin and the plans for the future.
