Integrated Land and Water Information System (ILWIS) is a geographic information system (GIS) and remote sensing software for both vector and raster processing. Its features include digitizing, editing, analysis and display of data, and production of quality maps. ILWIS was initially developed and distributed by ITC Enschede (International Institute for Geo-Information Science and Earth Observation) in the Netherlands for use by its researchers and students. Since 1 July 2007, it has been released as free software under the terms of the GPL-2.0-only license.[1][2] Having been used by many students, teachers and researchers for more than two decades, ILWIS is one of the most user-friendly integrated vector and raster software programmes currently available. ILWIS has some very powerful raster analysis modules, a high-precision and flexible vector and point digitizing module, a variety of very practical tools, as well as a great variety of user guides and training modules all available for downloading. The current version is ILWIS 3.8.6. Similar to the GRASS GIS in many respects, ILWIS is currently available natively only on Microsoft Windows. However, a LinuxWine manual has been released.[3]
In late 1984, ITC was awarded a grant from the Dutch Ministry of Foreign Affairs, which led to developing a geographic information system (GIS) which could be used as a tool for land use planning and watershed management studies. By the end of 1988, a DOS version 1.0 of the Integrated Land and Water Information System (ILWIS) was released. Two years later, ILWIS was made commercial with ITC establishing a worldwide distributors network. ILWIS 2.0 for Windows was released at the end of 1996, and ILWIS 3.0 by mid-2001. On 1 January 2004, ILWIS 3.2 was released as a shareware (one-month trial offer). Since July 1, 2007, ILWIS has been distributed as an open source software under the GPL-2.0-only license.[4]
Direct import of Aster satellite images level 1a and 1b, including all needed geometric and radiometric corrections. This functionality is integrated in the Import Map Wizard.
Stereopair from DTM - Stereo pair from DTM operation creates a stereo pair from a single raster map and a Digital Terrain Model (DTM). These stereo pairs have the same usability as the Epipolar Stereo Pair.
Patch 3.12a
August 2003
ID Grid map - creates a polygon map given a coordinate system and an attribute table. The polygon map consists of rectangular grid cells with a unique ID and can be linked to a table with attribute data when sample data is available.
Spherical Distance option was added to the operations Spatial Correlation, Cross Variogram, Nearest Point, Moving Average, Moving Surface, Kriging and CoKriging. This option calculates distances over the sphere instead of in a plane.
Export to ArcPad .PRJ - ILWIS coordinate systems can be exported to an ArcPad .prj file.

Layer visualization in ILWIS
Featuresedit
ILWIS uses GIS techniques that integrate image processing capabilities, a tabular database and conventional GIS characteristics.[5] The major features include:
Comprehensive set of image processing and remote sensing tools like extensive set of filters, resampling, aggregation, classifications. etc...
Orthophoto, image georeferencing, transformation and mosaicing
Advanced modeling and spatial data analysis
3D visualization[7] with interactive zooming, rotation and panning. "Height" information can be added from multiple types of sources and isn't limited to DEM information.
Animations of spatial temporal data stacks with the possibility of synchronization between different animations.
The next major version of Ilwis will be based on the Ilwis NG framework (in development). This framework aims at being a connection hub between various heterogeneous data and processing sources (local-remote). Integrating them in a consistent way and presenting them in a unified to the end users (at both programming and user interface level). The framework will be cross platform (ILWIS is now limited to Windows only) and will be deployable on mobile devices.
