Open Source GIS Applications

Open Source programs are applications of which you can access the source code. Listed here are available open source GIS-based applications you can download written for a variety of platforms and in various languages.

State of Open Source GIS
Intensive survey by Paul Ramsey published in September of 2007 that reviews open source GIS grouped by programming language. The survey looks at C, Java, .NET and web-based GIS.

EDBS Reader
A free (GPLed) reader software for the EDBS format has been released: EDBS_extra 2.0. This open source utility is written in ‘C’. The page is mostly in German.

fmaps
GIS/RS application for Linux and Gnome platforms. Open source code is available for downloading from this site.

GeoTools
GeoTools is an open source, Java GIS toolkit for developing standards compliant solutions. It’s modular architecture allows extra functionality to be easily incorporated. GeoTools aims to support OpenGIS and other relevant standards as they are developed.

GRASS
Geographic Resources Analysis Support System (GRASS) is the public domain GIS software application originally developed by the US Government.

MapServer
MapServer is an OpenSource development environment for building spatially enabled Internet applications. Compiles on most UNIX systems and will run under the Windows OS environment.

MITAB
MITAB is an Open Source (i.e. Free) C++ library to read and write MapInfo .TAB (binary) and .MIF/MID files. It is based on the OGR library which is an implementation of the Open GIS Consortium Simple Feature specification.

OpenEV
OpenEV is a library, and reference application for viewing and analysing raster and vector geospatial data. Download for Windows 98/NT/2000, Linux, Irix or Solaris systems.

OpenMap
OpenMap is a FREE JavaBeans software component for viewing spatial data. JavaBeans is a component specification for software written in the Java language. In contrast to other GIS software components which offer both data viewing and analysis capabilities, OpenMap is primarily for data viewing and offers very little in the way of analysis functionality. Open Source.

Quantum GIS
Also referred to as QGIS, Quantum GIS is an Open Source Geographic Information System (GIS) that runs on Linux, Unix, Mac OSX, and Windows.

rmap
rmap is a package that will allow you to generate images of the earth from a distance or fairly zoomed in. The code is a small C binary that reads a datafile of vectors to generate the image.

Tkgeomap
Tkgeomap is a set of extensions to the Tcl/Tk scripting language for manipulating and displaying geographic data.

Topology Framework .NET (TF.NET)
TF.NET represents a managed topology manipulation API capable of handling managed objects representation of topological entities based on other popular APIs, exposing it’s JTS-based common topology manipulation core to them. Supported external managed APIs include: OSGeo Feature Data Objects (FDO) geometries, OSGeo MapGuide Server (FDO-based) geometries and Autodesk ObjectARX geometries (a.k.a. entities) and, most recently, Oracle’s ODP.NET. Functions provided include: Spatial predicates (based on the DE-9IM model), Overlay functions (intersection, difference, union, symmetric difference), Buffer, Convex hull, Area and distance functions, Topological validity checking, Coordinate systems manipulation (transformations), Topological graphs manipulation, and more. TF.NET libraries are free, licensed under GNU LGPL and available for download from Google Code page.

Vhclmaps
Vhclmaps is a package of map viewers and spatial data servers that work with map databases.
