Data Structures Technical Panel - DSTP

The Data Structures Technical Panel addresses technical issues concerning the semantics of information and information processing including the structuring of data. It focuses on the development of those components of the DGIWG architecture related to an "information viewpoint". DSTP develops data product specifications, and database structures and content models for classes of information that may stored in "encyclopaedic databases" of geographic information from which data could be extracted to dynamically generate products or to support information services.
The responsibilities of the DSTP are to:

  • Develop standards for data structures for use in information exchange and as the information elements within data services.
  • Review interoperability requirements to determine which standards are required to support interoperability and to establish Projects to develop these standards.
  • Ensure that the developed standards satisfy the interoperability requirements while maintaining backward compatibility as required with existing DIGEST based data products, and to ensure that the standards are compatible with international standards and industrial implementation specifications.

The Technical Panel interfaces externally with the standardization efforts in ISO TC211, ISO/IEC JTC1 SC24, IHO, and other liaison organizations. This interfacing will include making use of formal liaison relationships and cooperative agreements as required, including participating in, and preparing papers for ISO committees.

The DSTP is chaired by the USA (National Geospatial Intelligence Agency)
