Questions & Answers
GML files: Frequently Asked Questions
What are GML files?
GML (Geography Markup Language) is an XML grammar for geographic features, defined by the OGC and published as ISO 19136:2007, with a later edition in 2020. The standard has been through several versions: 1.0 in 2000, 2.0 in 2001, 3.0 in 2002, 3.1.1 in 2004, and 3.2.1 in 2007, which became the ISO standard. A file normally has the .gml extension, although .xml is also used, and the media type is application/gml+xml. GML defines the building blocks, such as features, geometries, coordinate reference systems, and time, but it does not fix the objects of any particular domain. These are described in application schemas written in XML Schema, and a data file refers to its schema, which tells a program what the elements mean. A typical file is a collection of members, each of them a feature with a unique identifier, properties, and a geometry such as a point, a line, or a polygon, with the coordinate system named in the srsName attribute. The Web Feature Service standard of the OGC uses GML as its default encoding, and CityGML, a model for 3D city objects, is built on it. Because XML is verbose, GML files are large, but they are self-describing and easy to validate. The simple features profile limits the language to what simple map data needs.
Can reaConverter open GML files?

Do I need QGIS or ArcGIS to convert GML files?
