This section describes how to encode geospatial (geographic) features in GML. The encoding of spatial features using GML 2.0 requires the use of two XML Schemas: the GML Feature Schema (feature.xsd) and the GML Geometry Schema (geometry.xsd); with these two simple schemas it is possible to encode a wide variety of geospatial information.
The remainder of this sub-section introduces the two XML Schemas using UML notation. The following sub-sections provide an introduction to encoding geospatial information in GML 2.0, broken down as follows:
4.2 Encoding a feature without geometry
4.3 Encoding geometry
4.4 Encoding a feature with geometry
4.5 Encoding collections of features
4.6 Encoding associations between features ...
