The GML ( *.GML) file type is the standard document format for Geography Markup Language (GML), developed by the World Wide Web Consortium (W3C). The file extension saves geographic features in an XML file, enabling the development of a range of programs and applications that read and reprocess this data. The format is part of the wider GML technology, which includes implementations for ESRI's ArcGIS and Google Maps, allowing data to be cross-referenced and exchanged between these applications.
Common Uses
The GML file extension enables geographic information systems to function correctly, allowing familiar features such as roads, terrain models, parks, rivers and infrastructure to display on a world map. This information is available to program users, providing an accurate understanding of landscapes, political borders and points of interest from around the world. The World Wide Web Consortium have also created specifications on how GML should be implemented, ensuring a high level of accuracy no matter how it is used within other applications.
Alternate File Extension Types
The GML file type is similar to a range of other geographic map files such as KMZ, KML, GPX, SHP, GEOJSON and GEORSS. Each document type has its own benefits for different applications, with some being highly suitable for web-based mapping while others are best suited for desktop geographical programs. The ability to convert between these formats allows software creators and developers to provide a cross-platform experience within their applications.

Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .GML) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .GML extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .GML file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .GML extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .GML extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .GML file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .GML file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .GML file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .GML file) will be extended to the maximum.
It is also good to check
- if the .GML file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
