Open GIS® Specifications
NEC Aerospace Systems, Ltd.
OpenGIS Abstract Specification
Provide the framework or reference model for OpenGIS Implementation Specifications.
OpenGIS Implementation Specifications
Detail the agreed upon interfaces developed through OGC consensus process.
Use this information to build a software product, in order to communicate with any other
software that implements the same specification(s).
Recommendation Papers
Presents an official OGC position on a given topic, such as a draft Implementation
Specifications.
Published for public review and comment and may result in either Approved Abstract
Specifications or Approved Implementation Specifications.
Discussion Papers
Present technology issues being considered in the WGs and SIGs of the OGC TC,
to create discussion in the geospatial information industry on a specific topic.
These papers is not to be considered an adopted standard of any kind, and do not represent
the official position of the OGC nor of the OGC TC.
