GML Application Schemas

Geography Markup Language 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.
