1) Overview

The OpenGIS® Geography Markup Language Encoding Standard (GML) defines a data encoding in XML for geographic data and a grammar to express models of such data using XML Schema. GML provides a means of encoding geographic information for both data transport and data storage, especially in a Web context. It is extensible, supporting a wide variety of spatial tasks, from portrayal to analysis. It separates content from presentation (graphic or otherwise), and permits easy integration of spatial and non-spatial data. Clients and servers with interfaces that implement the OpenGIS® Web Feature Service Interface Standard read and write GML data. GML is also an ISO standard (ISO 19136:2007).
