1 RIEDP (Reuse and Interoperation of Environmental Data and Processes) A SISO Standard for Environmental Data sharing I/ITSEC 207 Briefing to SISO/OGC/USGIF Session 0

2 Who is talking to you? Jean-Louis GOUGEAT Currently Project Manager Flight Simulators / Simulation Centers Networking and other Research &Technology areas Previously Support of the French MoD in R&T areas French Army, Navy, Air Force Simulation Projects Studies for Staffs in Distributed Simulation Database Generation area Not an expert Trying to make the experts talk together! Chairman of the RIEDP PDG SISO Member since 996 jlgougeat@sogitec.fr

3 Sogitec at a glance Simulators for Training Mirage Family (F, -5, D, -9, H, ) Rafale Omnirole A/C Helico (NH90, Dauphin, Cougar) LVC Training Users France FAF, Army Light Aviation, Navy Foreign users NATO Middle East (Egypt, Qatar, UAE, ) Taiwan India 2

4 Synthetic Environment Various Contributors Simulator Visual System CGF Simulator 2 Simulator 3 Real Actor Exercise Controlller HLA or Other 3

5 4 Synthetic Environment Requirements for an Aircraft Simulator

6 Synthetic Environment Requirements / Fidelity Not to mention different internal models in different simulation systems... 5

7 Building a Simulator Database Target Databases Visual DB Source Data Database Creation Radar DB IR DB Other Sensors CGF DB Maps Others 6

8 Additional issues for Distributed Simulation Reuse Correlation Interoperability. Duplication of efforts Duplication of Cost Time to market Sim A - Provider Consistency? Schedule? Sim B - Provider 2 Sim C Provider 3 M&S Interoperability is even more critical in the International Arena with Multiple Providers and Multiple M&S Solutions 7

9 M&S Interoperability What it is Not The same Product and associated Solutions for everyone Does not work, certainly not in the international arena Puts innovation at risk What product to choose? Single solution sufficient? What it is Consistency in Modelling, associated Data and Semantics at Component Level Allowing Components to work together at System & System-of-Systems Levels Fostering Multiple-Provider Solutions (e.g. : I/ITSEC/OBW Federations) Interoperability relies on Appropriate Standards 8

10 Data Transformation Process Two main phases Target Databases Source Data Phase Data Cleaning & Enhancement Database Synthetic Creation Environment Intermediate Data Phase 2 Target DBs Generation Visual DB Radar DB IR DB Other Sensors Standardize here at appropriate Intermediate stages CGF DB Maps Manual Work: 80% 20% Computation Time: 20% 80% Others 9

11 Data Transformation Process Possible Improvement The process may be made more efficient in MTDS If Source data is comprehensive and consistent Within each and between the layers If previous creation efforts may be reused At Source Data Level (Linked to GIS World) At Intermediate Level Requires Common Processes, Representations, and Formats at this level MTDS : Mission Training via Distributed Simulation Reuse of Intensification efforts Data Diversity Data Quality Discovery & Access Metadata Hardly Reusable (Unless same target platforms) 0

12 Key Topics for Database sharing When reusing data from a partner, you need to know How the database was built How the database is represented How the database is spatially referenced How the database is structured How the database is organized on the media How well the database conforms to Standards Information about the data product Tasks performed or not Conceptual Model Spatial Reference Model Physical data model Folders and formats Compliance & Profiles Metadata No existing solution fully satisfies all of these requirements

16 Take away RIEDP Takes benefit of the lessons learnt from all related Initiatives Reuses and relies on existing standards (such as SEDRIS ISO/IEC standards and PNG ISO/IEC standard), as well as formats commonly used in the community Represents the best common denominator by providing a Reference Process Model (RPM), a formal Reference Abstract Data Model (RADM), relying on use of existing Formats, specifying unique Profiles, and focusing on metadata and attribution semantics Does not impose internal solutions on producers Provides a common data sharing approach that relies on a formal abstract data model (RADM), along with specific metadata and attribution (Product #2) This allows the best sharing of data, independently from target applications implementation, with a current scope addressing static terrain and Visual System (Flight Sim) data 5
