ILWIS 3.4 Open

ILWIS for Windows is a Windows-based, integrated GIS and Remote Sensing application. ILWIS integrates image, vector and thematic data in one unique and powerful desktop package.
ILWIS will provide you a wide range of feautures including import/export, digitizing, editing, analysis and display of data, as well as production of quality maps.
ILWIS functionality for vectors includes: digitizing with mouse and/or digitizer, interpolation from isolines or points, calculation of segment or point density, pattern analysis.
ILWIS functionality for raster includes: distance calculation, creation of a Digital Elevation Model (DEM), calculation of slope/aspect, deriving attribute maps, classifying maps, manipulating maps with iff-statements, with Boolean logic, crossing maps, etc.
For satellite imagery: creation of histograms, color composites, sampling and classification, filtering, multi-band statistics.
Furthermore ILWIS provides import and export routines, editing of point, segment, polygon and raster maps, change of projection/coordinate systems of maps, and output possibilities with annotation.
With Windows, you can start one operation and keep it running while you start one or more additional applications. This is a sort of multitasking. You may work with both Windows and DOS application programs, you can perform one or more ILWIS calculations in the background and at the same time display maps, run other ILWIS operations, print, etc.
