Welcome to MapTools.org
a resource for users and developers in the open source mapping community, and a home to many open source projects. The projects that are hosted here offer essential services including: latest downloads, CVS repositories for source code, bug lists, community mailing lists, and project documentation.

Some of the links here are to selected open source projects hosted elsewhere that are related to the projects hosted on MapTools.org.

Other Resources


The Open Source Geospatial Foundation's goal is to support and build the highest quality open source geospatial software.


SpatialReference.org is an excellent resource to find specific projections, in various formats (EPSG, Proj4, prj, WKT, JSON).

Packaged Tools and Utilities


MapServer for Windows - A preconfigured Web Server environment that includes MapServer and other useful utilities, specifically for Microsoft Windows. (now hosted on ms4w.com)


A self-contained bootable DVD, USB thumb drive or Virtual Machine, that allows you to try a wide variety of Open Source geospatial software without installing anything.

Web Tools


A comprehensive framework for building MapServer-based Web mapping applications using SOAP Web services.


A highly customizable and adaptable environment for deploying and managing Web mapping applications.


A higher-level component framework for MapServer, to help in building rich Python and JavaScript-based mapping applications.


An application development framework for both MapServer and MapGuide Open Source built primarily in JavaScript.


A JavaScript toolkit that brings together the powers of OpenLayers and the EXT JS framework.


A JavaScript Web client application built on OpenLayers and MapServer, with customizable tools and services.


An Open Source package that provides a javascript API for developing highly interactive web-mapping interfaces. It has been developed to work with MapServer, but can be easily integrated with other software packages.

A CGI program that produces GIF images of virtually any type of chart from a set of input parameters.

PHP MapScript

A PHP dynamically loadable module that makes MapServer's MapScript functions and classes available in a PHP environment.

Desktop Tools


An open source GIS with raster, topological vector, image processing, and graphics production functionality.


A library and reference application for viewing and analysing raster and vector geospatial data.

Quantum GIS

An open source GIS that uses the OGR and GDAL libraries to view several vector and raster formats, and includes support for PostGIS tables and GRASS digitizing.


An open source viewer/editor that brings together internet, database, and file-based spatial data.

Utilities and Libraries


A C library that makes Arc/Info (binary) vector coverages appear as ASCII E00 files.


DGNLib is a small C/C++ library for reading and writing DGN files.
