The Community Edition of the GLG Map Server is a fully functional version of the GLG Map Server for the CGI and Fast-CGI deployment on a web server. It may also be used as a stand-alone utility to generate map images. Click here to browse the image gallery, or click here to run on-line GIS demos.
The GLG Map Server is compact and self-contained, with one executable and no dependencies on other libraries and packages. It is easy to set up, and a sample dataset with all setup files is included with the download. Sample scripts for generating map images without the web setup are also included. All map server features and options are always enabled and may be customized by editing ASCII configuration files. The download also includes an HTML sample of a JavaScript-based GIS viewer which allows zooming, panning, changing projection and selecting layers on the map.

The GLG Map Server complies with the OpenGIS standard and
is optimized for run-time performance. It supports rendering of millions of points, both raster, vector and elevation data, rectangular and orthographic projections, unlimited layering, full alpha-blending, transparency and dynamic attribute thresholding. The map server is optimized for displaying maps of both the whole globe and small regions, supports hierarchical tiling, tile cache and automatic layers selection based on zoom thresholds. It also provides support for elevation data and queries of elevation at particular lat/lon location. Click here for more information.

The GLG Graphics Builder provided with the Community Edition
of the GLG Toolkit may be used as a fast prototyping tool for the Community Edition of the GLG Map Server. You may download the Community Edition of the Toolkit and use its Graphics Builder as a GIS Viewer to test and debug the map server setup interactively. Click here for the instruction on how to use the Graphics Builder for such prototyping.

The map server library is also available for embedded ARM devices, including the Beagle Bone and Raspberry Pi boards. The library supports all map server features and makes it possible to deploy a GIS application on a stand-alone embedded system.

GLG Map Server: Community Edition FAQ

I am developing XYZ project, can I use the Community Edition of the map server for it?

I am a consultant hired by the company to develop a web application for viewing a particular kind of GIS data on the web. Can I use the Community Edition?

What kind of support is provided for the Community Edition?

If I use the free Community Edition now, is there a possibility I will have to pay a fee in the future?

What platforms are supported for the Community Edition?
I am developing XYZ project, can I use the Community Edition of the map server for it?
A commercial project is defined as an application or web service that is developed or used by a commercial entity as part of its business activity, either for profit or for advertising and promotion purposes.

If you develop an application or web service for a non-commercial entity, and it will be available to all users free of charge, you can use the Community Edition of the GLG Map Server.

1.2 I am a consultant hired by the company to develop a web application for viewing a particular kind of GIS data on the web. Can I use the Community Edition?
If the application is developed for a non-commercial entity and will be freely available for all users, the Community Edition of the Map Server may be used for it.
1.3 What kind of support is provided for the Community Edition?
The Community Edition is provided as is. Every release of the GLG Map Server fixes bugs reported in either the Commercial or Community Editions of Map Server, and we always try to resolve any issues as fast as possible in both versions. However, if you want to get commercial support with a guaranteed response time, you may want to consider purchasing a commercial version that includes support services.

GLG Toolkit Community Edition Discussion Group may be used for posting questions that may be answered by the community experts as well as the GLG team.
1.4 If I use the free Community Edition now, is there a possibility I will have to pay a fee in the future?
No. You are getting an executable which you can use for free as long as you do not sell a commercial application. This is different from licensing a format, like GIF, where the license can change.  Once you have downloaded the map server executable, you can keep using it indefinitely under the terms of the GLG Community Edition License.
1.5 What platforms are supported for the Community Edition?
The Community Edition is supported for all platforms on which the GLG Toolkit is available. Click here for a complete list of supported platforms.
