Theory FAQ

• What is the Synthetic Environment?
• What is representational polymorphism?
• What is the difference between a data representational model and a data format?
• What is topology, why is it needed and who uses it?

---

Data Representation Model Content FAQ

• Briefly describe the SEDRIS data representation model and how it is organized.
• Why does SEDRIS show/contain a "tank" model within the data representation model? The submarine world doesn’t include targets or weapon systems as a part of the ocean environment.
• How does SEDRIS represent different items such as a tree or sound velocity profile (SVP)?
• What do environmental databases contain? Are they like a MicroSoft^® Access database?
• Why are there many ways to organize objects in SEDRIS?

---

SEDRIS Usage FAQ

• Does a data provider have to fully populate the data representation model to generate a transmittal?
• Does SEDRIS solve the interoperability and correlation problem?
• How do I get training in the use of SEDRIS?
• Is SEDRIS used for the generation of environmental databases?
• What if the kind of representation that I need is not in SEDRIS?

---

Data Interchange FAQ

• How were environmental data interchanges performed in the past? How are they now done with SEDRIS?

---

Comparison FAQ

• How is SEDRIS different from VRML?
• How is SEDRIS different from Project 2851 and its definition of SIF?
• How is SEDRIS different from High Level Architecture (HLA)?

---

EDCS FAQ

• Is the EDCS a tool for the exchange of real-world geo data, or is it focused on simulation with synthetic data?
• Is the EDCS intended as a replacement for specialized coding catalogues or formats developed by DIGEST, IHO, WMO, ICAO, etc.?

---

Real-Time Simulation FAQ

• Can the STF format be used as a native format for a real-time aerial (and ground) simulation with no performance hit in comparison, for example, to running with OpenFlight or CTDB formats, or is the STF only a means to exchange data from different native terrain database formats such as OpenFlight and NIMA DTED?

---

Version Numbering FAQ

• What is the reasoning behind SEDRIS version numbering and how does this affect software compatibility?

---

Creating CTDBs FAQ

• How can I find information on the Compact Terrain Database (CTDB) format?
• How do I convert formats such as Vector Product Format (VPF) and Digital Terrain Elevation Data (DTED) into STF, so that I can then use the STF to CTDB Converter to create CTDBs?
• What if I also need to include Food and Agriculture Organization (FAO) Soils, and Global Land Cover Characteristics (GLCC)?
