These standards are related to the presentation of geographic information on maps:
- ISO 19117:2012, Geographic information -- Portrayal, provides a schema for specifying symbols and mapping them to an application schema.
- OGC Styled Layer Descriptor (SLD) defines an encoding that extends the WMS standard to allow user-defined symbolization and coloring of geographic feature and coverage data. SLD addresses the need for users and software to be able to control the visual portrayal of the geospatial data served over the Web.
- OGC Symbology Encoding (SE) defines an XML language for styling information that can be applied to digital feature and coverage data.
