Geography Markup Language

Geography Markup Language

The Geography Markup Language is the XML grammar defined by the Open Geospatial Consortium to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet...

 provides the basis for domain- or community-specific "Application Schemas", which in turn support data interoperability within a community of interest. Application schemas are normally designed using ISO 19103 conformant UML, and then the GML Application created by following the rules given in Annex E of ISO 19136.

Following is a list of known, publicly accessible GML Application Schemas.
