Symbology Encoding

This Specification defines Symbology Encoding, an XML language for styling information that can be applied to digital Feature and Coverage data. This document is together with the Styled Layer Descriptor Profile for the Web Map Service Implementation Specification the direct follow-up of Styled Layer Descriptor Implementation Specification 1.0.0. The old specification document was split up into two documents to allow the parts that are not specific to WMS to be reused by other service specifications.

Coordinate Transformation Service

The OpenGIS® Coordinate Transformation Service Standard (CT) provides a standard way for software to specify and access coordinate transformation services for use on specified spatial data. This standard addresses a key requirement for overlaying views of geodata (“maps”) from diverse sources: the ability to perform coordinate transformation in such a way that all spatial data are defined relative to the same spatial reference system.


A Subcommittee is a standing group (organizationally, a subgroup of the Technical Committee or the Planning Committee) of individuals composed of members of the TC or PC and Invited Guests, with a mission to provide recommendations to the TC or PC in some general area. A Subcommittee does not generate a Standard nor do they work on a Standard.
