GLG Map Server - Free Community Edition GLG Map Server sample: Orthographic projection

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, and may also be used as a stand-alone utility to generate map images. Click here to browse the image gallery or run on-line demos.

The Community Edition includes all features that are available in the commercial version and is provided free of charge for non-commercial use. It is provided as a service to the software development community for developing non-commercial projects that do not have resources to purchase a commercial license. Click here to download.

The GLG Map Server is compact and self-contained, with one executable and no dependencies on other libraries and packages. It is easy to setup, 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 by customized by editing ASCII configuration files. An HTML sample of a JavaScript-based GIS viewer that allows zooming, panning, changing projection and selecting layers on the map is also provided with the download.

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 demo version 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 demo version of the Toolkit and use its Graphics Builder as a GIS Viewer to test and debug the map server setup interactively.

I am developing XYZ project, can I use a free version 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 free version 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 free version?
If the application is developed for a non-commercial entity and will be freely available for all users, the free version of the Map Server may be used.
1.3 What kind of support is provided for the free version?
The free version is provided as is. Every release of the GLG Map Server fixes bugs reported in either the commercial or free version 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 might want to consider purchasing a commercial version that includes support services.
1.4 If I use the free version 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 conditions of the download.
1.5 What platforms are supported for the free version?
The free version is supported for all platform on which GLG Toolkit is available. Click here for a complete list of supported platforms.
