ILWIS (Integrated Land and Water Information System) is a GIS / Remote sensing software for both vector and raster processing. ILWIS features include digitizing, editing, analysis and display of data as well as 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, but since 1 July, 2007 it has been distributed under the terms of the GNU General Public License and is thus free software. [. Having been used by thousands of students and hundreds of professors for more than 2 decades, ILWIS has become 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 3.5 Open.Similar to the GRASS GIS in many respects - but more user-friendly -, ILWIS is currently only available natively only on Microsoft Windows. However, a Linux WINE manual has been made available.

History

In late 1984, ITC was awarded a grant from the Dutch Ministry of Foreign Affairs, which led to the development of 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 the 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 1st January 2004, ILWIS 3.2 was released as a shareware (one month trial offer).Since July 1st 2007, ILWIS has been distributed as an open source software under GPL license.Cite web

Roadmap

ILWIS building currently relies on the Microsoft Visual 2008 compile environment which will be switched over to the GCC compiler. After successful completion of the migration to GCC, the plan is to break down ILWIS Open into individual components. To reuse and deploy ILWIS’ GIS and image processing functionality also in spatial data infrastructures (SDI), its functions will be offered in an open framework as distributed services, in two ways:
# As java service proxies accessible to programmers and
# As OGC - based services accessible to client applications. The framework supports the search and access of services through a service registry and can be used together with client tools like uDig.

Features

ILWIS uses GIS techniques that integrate image processing capabilities, a tabular database and conventional GIS characteristics. [Cite book

Criticisms

ILWIS Open Source, is very user-friendly, and it has very powerful GIS analysis modules, but it currently lacks the Importing modules through proprietary PCI's GeoGateway, which has been removed in version 3.4 open and later. The available GDAL library is not so well integrated. [Cite web
