Apr 21, 2016 -- Members of the Open Geospatial Consortium (OGC®) request comments on the draft charter for an OGC Coordinate Reference System (CRS) Standards Working Group (SWG).

The purpose of the OGC SWG is to revise Abstract Specification Topic 2 - Spatial Referencing by Coordinates to the state of an adopted OGC standard and an identical ISO International Standard. This will be achieved by processing comments received during the public comment period and ensuring that the standard is consistent with OGC business plans.

This revision will accommodate advances in modern geodesy, to include the definition of CRSs having a "dynamic datum" - to compensate coordinate changes with time due to tectonic activity, as well as enhanced capabilities for derived CRS definitions (such as a vertical CRS defined through a geoid model). The work will also correct some minor errors. The technical content of OGC Abstract Specification Topic 2 and ISO 19111:2007 are currently identical. In the interests of interoperability ISO and OGC standards need to remain aligned. The work will be conducted jointly with ISO Technical Committee 211.

The draft charter is available for review at portal.opengeospatial.org/files/68188. Comments should be sent via email to Email Contact and are due by DATE. The OGC and the SWG welcome all interested parties.

About the OGC

The OGC is an international consortium of more than 515 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC standards support interoperable solutions that "geo-enable" the Web, wireless and location based services, and mainstream IT. OGC standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.
