The Open Geospatial Consortium (OGC) seeks public comment on the early development of a Symbology Conceptual Core Model (SCCM).

The Symbology Conceptual Core Model (SCCM) is an abstract, modular, and extensible model, with no encoding dependency, used for the portrayal of geographical data. The SCCM aims to offer a consistent approach to specifying data portrayal and symbology rules that can be applied to geospatial datasets as well as online geospatial data and mapping services. Existing OGC standards for styling and symbology can only be used with a few OGC standards (e.g. Web Map Service), so a more general and portable symbology model is required for use across the broad OGC standards baseline.

The SCCM aims to:

  • provide the flexibility required to achieve adequate cartographic styling for a variety of information communities; e.g. aviation symbols, weather symbols, thematic maps, etc, and;
  • achieve a high level styling interoperability without encoding dependencies (one symbology model, many encodings).


Potential implementations of the SCCM are expected to enhance OGC standards such as the Web Map Service, Web Feature Service, GeoPackage, and others. By sharing a common core, and using an extension mechanism, integration of these standards for the purposes of cartographic representation could be greatly simplified.
