Comprehensive collection of GIS programs and tools that is updated daily. Most are either freeware or open-source. They are organized in alphabetical order.
GMT is an open source collection of 60 tools for manipulating geographic and Cartesian data sets (including filtering, trend fitting, gridding, projecting, etc.) and producing Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots via contour maps to artificially illuminated surfaces and 3-D perspective views. GMT supports ~30 map projections and transformations and comes with support data such as GSHHS coastlines, rivers, and political boundaries. GMT is developed and maintained by Paul Wessel and Walter H. F. Smith with help from a global set of volunteers, and is supported by the National Science Foundation. It is released under the GNU General Public License.
GpsDrive s a car (bike, ship, plane) navigation system. GpsDrive displays your position provided from your GPS receiver on a zoomable map. The maps are autoselected for best resolution depending of your position and can be downloaded from the Internet. Speech output is supported if the "festival" software is running. All GPS receivers supported by gpsd should be usable.
GpsDrive is written in C with use of the GTK+ toolkit under the GPL license, and runs with Linux, Mac OSX, and FreeBSD.
Grass GIS New Release - Just released version 6.3 is now Windows and Mac ready. Previous versions worked with Unix based machines and Macs, but required an interpreter to work with Windows. It is a free software Geographical Information System (GIS) with raster, topological vector, image processing, volume voxel management/visualization, 2D/3D vector engine with vector network analysis and graphics production functionality that operates on various platforms through shell and a graphical user interface.
gvSIG is a free open-source tool oriented to manage geographic information. It is characterized by a user-friendly interface, with a quick access to the most usual raster and vector formats. In the same view it includes local as well as remote data through a WMS, WCS or WFS source.

iGMT: Interactive Mapping of Geoscientific Datasets - This program is intended to make working with the Generic Mapping Tools (GMT) easier. iGMT provides a graphical user interface for GMT and is written in the Tcl/Tk computer language. Besides supplying a user friendly way of handling GMT, iGMT comes with built-in support for many different geoscientific data sets, such as topography, gravity, seafloor age, hypocenter catalogs, plate boundary files, hotspot lists, CMT solutions etc.
InteProxy is a tool that adds secure transmission via SSL a well as user authentication to those OWS-based applications that that do not support these security features.
Interactive Mapping of Geoscientific Datasets (iGMT) provides a graphical user interface and was built using the Tcl/Tk computer language. Besides supplying a user friendly way of handling GMT, iGMT comes with built-in support for many different geoscientific data sets, such as topography, gravity, seafloor age, hypocenter catalogs, plate boundary files, hotspot lists, CMT solutions etc.
JCS Conflation Suite (JCS) is an API and set of interactive tools which perform conflation on spatial datasets.
JEEPS Library is intended as both a library and a development system for GPS and related software. It consists of documented C functions for communication with GARMIN GPS devices and for post-processing of the information received. The library also contains functions for conversion of datums using Molodensky and cartesian methods and mapping functions including transverse mercator projections. The UTM coordinate system is implemented as are other more parochial systems including the UK Ordnance Survey national grid (with map codes). Eighteen map projections and their inverses are given. NMEA data capture routines are included. An application (program) is distributed with the library in order to show the library functionality and how to use it.
JUMP Unified Mapping Platform (JUMP) is a GUI-based application for viewing and processing spatial data. It includes many common spatial and GIS functions. It is also designed to be a highly extensible framework for developing and running custom spatial data processing applications.
KFlog is a soaring-pilot-software for KDE. It is used to display, analyze and evaluate flights logged with a gps-logger. Different values of a flight-point can be displayed in the map, like altitude, cycling, speed and vario. There is a maproom-page where you can download Aeronautical, Ground- and terrain- and additional data for maps.
LookOUT - The online map connector for MS Outlook,
LookOUT by IDELIX is a great new free add-in for Microsoft Outlook that streamlines your daily planning by eliminating the tedious task of copying addresses from your Outlook contacts and pasting them into an online mapping application.
LookWMS by IDELIX is a Web Map Client that implements the OpenGIS WMS specification and enables users to access geospatial data from WMS servers over the Internet. Some of the interesting features of our client include: The ability to access and display information from multiple servers at the same time, for true multi-layer interaction; The ability to cache data locally to work off-line when a connection is not available and improve mobile workforce productivity; and The ability to access GeoTIFF files from your local machine or from a remote server. You can save your GeoTIFF files locally for quick reference in the future.
Mapbender is the software and portal site for geodata management of OGC OWS architectures. The software provides web technology for managing spatial data services implemented in PHP, JavaScript and XML.
MapEdit, a low cost solution (free to educational and non-profit organizations) for making image maps come alive. Simple image maps and html still outshine many mapservers.
MapGuide Open Source is a web-based platform that enables users to quickly develop and deploy web mapping applications and geospatial web services. MapGuide features an interactive viewer that includes support for feature selection, property inspection, map tips, and operations such as buffer, select within, and measure.
