Simple Features for OLE/COM

The three OpenGIS® Simple Features Implementation Specifications (one each for OLE/COM, CORBA, and SQL) define interfaces that enable transparent access to geographic data held in heterogeneous processing systems on distributed computing platforms.

The Simple Feature Specification application programming interfaces (APIs) provide for publishing, storage, access, and simple operations on Simple Features (point, line, polygon, multi-point, etc). The purpose of these specifications is to describe interfaces to allow GIS software engineers to develop applications that expose funct...

Simple Features SWG


Herring, John (Oracle USA)
Scarponcini, Paul (Bentley Systems, Inc.)

Group Description:


1.    ISO Simple Features

A Standard working group is being formed to work on the ISO version of the Simple Features specification. The intent is to create a fully harmonized standard so that the OGC and ISO standards and the SQL/MM Part 3 spatial versions are harmonized at the end of the work of the  SWG. A summary SWG description is given here and expanded below:

Spatial Data Quality Certification Concept Development

This project is for the Concept Definition (CD) phase of a Spatial Data Quality Certification Initiative in OGC’s Interoperability Program. The main outcome of the CD Phase will be a Feasibility Report defining the Initiative. The Feasibility Report will be used to recruit additional sponsors for the execution phase of the Initiative. In particular the Feasibility Report will be ready for discussion at the INTERGEO conference in Munich, 9-13 October 2006.

Special Interest Groups

Special Interest Groups (SIG) provide a forum for the discussion of business and technology interoperability requirements for given geographic region or information community.

Styled Layer Descriptor

The OpenGIS® Styled Layer Descriptor (SLD) Profile of the OpenGIS® Web Map Service (WMS) Encoding Standard [http://www.opengeospatial.org/standards/wms] defines an encoding that extends the WMS standard to allow user-defined symbolization and coloring of geographic feature[http://www.opengeospatial.org/ogc/glossary/f] and coverage[http://www.opengeospatial.org/ogc/glossary/c] data. SLD addresses the need for users and software to be able to control the visual portrayal of the geospatial data. The ability to define styling rules requires a styling language that the client and server can bo...


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.
