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)
