Good news for the GIS community, the ILWIS GIS Software from ITC (International Institute for Geo-Information Science and Earth Observation) has migrated to Open Source software under the 52 ° North initiative since July 1, 2007.
ILWIS was built as the Integrated Land and Water Information Systems, but this software is not limited to Natural Resource Management course. ILWIS can also be used for risk assessment and urban planning. For raster data users this is good news because in addition to its ability in GIS data processing but also good in the processing of raster data. Sautsagala even dare to say "ILWIS is very good in dealing with raster data but not so much for vector. ESRI ArcGIS does much better in vector based data but poor in raster "
