Synthetic Environment Data Representation and Interchange Specification SEDRIS

1
Synthetic Environment Data Representation and
Interchange Specification (SEDRIS)

• MSEA SIW Session
• September 16, 1999

2
Goals for Technology Development

• Articulate and capture the complete set of data
  elements and associated relationships needed to
  fully represent the physical environment.
• Support the full range of simulation applications
  (e.g., computer-generated forces, manned, visual,
  and sensor systems) across all environmental
  domains (terrain, ocean, atmosphere, and space).
• Provide a standard interchange mechanism to
  pre-distribute environmental data and promote
  database reuse and interoperability among
  heterogeneous simulations.

3
Where we are today!

• Public Release Version 2.5.1 (Software
  Developers Kit)
• On-going technology insertion and cooperation
• SEDRIS is STRICOM policy
• All future procurement actions which
  require the development of synthetic natural
  environment databases for use in any simulation
  system or component, such as image generators,
  semi-automated forces, sensor simulations, etc.,
  shall specify that all data used in the
  development of SNE databases, including the final
  database product (prior to runtime compilation)
  be delivered by the contractor via the SEDRIS
  interchange mechanism as the exchange means for
  SNE data between applications and other programs,
  in addition to the usual runtime format(s)
  specific to the individual program.
• Data representation model is stable
• Data Coding Standard in place
• Spatial Reference Model in place
• Successful interchange with and without format
• Standardization Documentation in preparation

What Associates Do...

• Learn to speak SEDRIS - enhanced Rumbaugh
  notation
• Generate a mapping document for their native
  format(s) or assigned government format(s) that
  ensures the data representation model and coding
  standard can handle all data requirements
• Develop software to convert native data into
  SEDRISand back to check completeness of the
  interchange
• Participate in SAMs and associated interchange
  experimentsto exchange ideas and cooperatively
  define and develop SEDRIS technology components
• Share with other associates all non-proprietary
  (native format) utilities and applications that
  support SEDRIS interchange

Integrated Strategy Requirements

• Fully define the SEDRIS Interchange Mechanism
• Need comprehensive superset of conversion
  software for Operational Providers (particularly
  government) for all types of natural environment
  data
• Develop robust capability to perform coordinate
  system transformations of gridded data (Spatial
  Reference Model)
• Determine optimal mechanisms to interpolate
  gridded data and incorporate capability into
  SEDRIS
• Develop software to produce ESG capstone SEDRIS
  transmittal
