Application | GML is an Extensible Markup Language (XML) encoding for transport and storage of geographic information.It is typically used for vector geometry with associated attribute data, such as, a road network or cadastral data. GML is specifically powerful for web processing of geo-spatial data. |
Implementation benefits | GML is a human readable and machine ‘processable’ encoding which makes it ideal for web data dissemination. GML is based on XML, which brings a number of advantages, such as, XML providing a method for verifying data integrity; the XML structure allowing easy integration of GML data with non-spatial data; and XML transformations. GML allows topology to be encoded in the schema. |
