GRASS (Geographic Resources Analysis Support System) Developer: GRASS Development Team Latest release: 6.2.2 / July 16, 2007 OS: Linux, MS-Windows, Mac OS X, POSIX compliant systems Genre: Geographic information system License: GPL (General Public License ) Website: http://grass.itc.it22

GRASS is an open source, Free GIS with raster, topological vector, image processing, and graphics production functionality that operates through a GUI and shell in the Window System. The recent GRASS 6 release introduces: • A new topological 2D/3D vector engine and support for vector network analysis. •Attributes are managed in .dbf files or SQL-based DBMS such as MySQL, PostgreSQL/PostGIS, and SQLite. •Capable of visualizing 3D vector graphics data and voxel (is a volume element, representing a value on a regular grid in three dimensional space), volumes.

•Supports an extensive range of raster and vector formats through the binding to GDAL/OGR libraries, including OGCconformal (Open Geospatial Consortium). •Simple Features for interoperability with other GIS. It also supports Linear Reference System. •GRASS is one of the eight initial Software Projects of the Open Source Geospatial Foundation.

MapServer is an open source internet map server, which runs as a CGI (Common Gateway Interface (CGI) is a standard protocol for interfacing external application software with an information server, commonly a web server. This allows the server to pass requests from a client web browser to the external application. The web server can then return the output from the application to the web browser) program. MapServer was originally developed with support from NASA, which needed a way to make its satellite imagery available to the public.

ILWIS (Integrated Land and Water Information System) Developer: 52° North Latest release: 3.4 Open / July 1, 2007 OS: MS-Windows Genre: Geographic information system License: GPL Website: 52°North Product page, www.itc.nl/ilwis/downloads/ilwis32.asp

ILWIS is a GIS / Remote sensing software that integrates image, vector and thematic data. ILWIS features include: •Digitizing, •Editing, •Analysis and display of data •Production of quality maps. ILWIS was intially developed and distributed by ITC Enschede (International Institute for Geo-Information Science and Earth Observation) in the Netherlands as shareware, but since 1 July 2007, it is distributed under the terms of the GNU General Public License and is thus free software.

MapInfo combines software, data (both spatial and non spatial) and consultancy with project management, systems design and development, training and support. MapInfo produces a wide range of software: •Spatial Cartridges for databases (Spatial Ware) •Routing (Routing J Server) •Geocoding (Map Marker) •Site Analysis (Any Site) •Risk Analysis, (TargetPro),

ERDAS IMAGINE remote sensing application

raster graphics editor

and

•Designed by: Leica Geosystems Geospatial Imaging. •Latest version : 9.1.

•It is aimed primarily at geospatial raster data processing that allows the user to display and enhance digital images.

•It is a toolbox allowing the user to perform numerous operations on an image and generate an answer to specific geographical questions.

•By manipulating data placement in imagery, it is possible to see features that would not normally be visible.

•The level of brightness, or reflectance of light from the surfaces in the image can be helpful with vegetation analysis, prospecting for minerals etc.

•Other usage examples include linear feature extraction, generation of processing chains ("models" in ERDAS IMAGINE), import/export of data for a wide variety of formats, orthorectification of data and so forth.
