The GML file is an XML grammar that is used to express geographical features, and it mainly serves as the modeling language for different geographical systems. It also works as an open interchangeable format for the internet for geographic transactions. These two purposes combine to make up a strong and reliable system.
GML data is by Galdos Systems, and it gets support from the Open Geospatial Consortium. A file in this format uses a GML schema description, and this enables users to describe generic geographic data sets that have polygons, lines, and points. It is in two parts which are the schema and the documents that have the real data.
You can use a file in this format to describe bridges and highways instead of lines, polygons, and points. It encourages users to use one system so that it can be easier to describe distinct features without confusion on contradictions. By using the same system, the distinct features do not change despite the time or position in which they are being viewed. There are also extensions of this system with specialization, and these extensions provide more accurate data, especially when they are being used in the right manner.
