Spatial Reference Model (SRM) Product Development
Group (PDG)

SRM PDG Purpose

• To review the SRM technologies and its software
  implementation
• To provide comments, modifications, improvements,
  for incorporation into the ISO/IEC standard
• Once the results are satisfactory to SISO, to
  recognize the SRM as a formal SISO product,
  recommending and encouraging its use within the
  MS community
• The product will reference appropriate ISO/IEC
  specification standards
• To encourage and guide the development of
  utilities (software, mapping documents, use
  guides, etc.) that will enhance usability of the
  SRM

Value to SISO Community (1 of 2)

• Leverage an extant SEDRIS technology across a
  broader domain than environmental data
  representation and interchange
• Broadened domain of interest includes, e.g.
• Any MS data including location/orientation
  information
• Non-environmental runtime (e.g., entity
  locations, ranges, etc.)
• Environment runtime (e.g., dynamic environment
  updates)
• To be accomplished by utilizing the formal SISO
  product nomination/development process
• Reference products based on an existing body of
  standards work with ISO
• Fast-track efforts within SISO to develop
  guidance products to standardize Reference
  Implementations

4
Value to SISO Community (2 of 2)

• SISO Product would add value to the ISO/IEC
  specification standards in two fashions
• Scoping the recommended uses of the specification
  standards within the MS community, including use
  cases
• Extending (or refining) the specification
  standards for use within the MS community

5
Value to MS Community

• To increase interoperability, e.g.
• Standard coordinate conversion/transformation for
  all SOMs/FOMs
• Support for improved interoperability between MS
  and C4ISR systems
• To increase federate accuracy and performance
• More accurate and efficient coordinate
  conversion/transformation
• To provide rational structure for community data
  modeling
• Improved understanding of spatial reference frame
  selection implications
• Eventual elimination of use of inappropriate
  spatial reference frames
• Improved integration of models from multiple
  sources
