1. SEDRIS™ : What it is and is not
|
Article by: Farid Mamaghani
BACKGROUND
Environmental data is an integral part of many of today’s information technology applications. The use of environmental data will grow substantially as availability and access to such data increases and as tools for manipulation of environmental data become less expensive and more sophisticated....

2. History & Development Philosophy in SEDRIS™
|
Article by: Jim Shiflett
SEDRIS was initiated in 1994 as a program by STRICOM (PM CATT) and DARPA (STOW) dealing with the complex problem of environmental representation and exchange. The long-standing problem of environmental representation was recognized in the mid 1980’s with Project 2851 and the DARPA SIMNET program. Project 2851 was a joint service program lead by the Air Force. ...

3. SEDRIS™ Technology Components
|
Article by: Farid Mamaghani
THE MAKE UP OF SEDRIS™
SEDRIS is fundamentally about two key aspects: (1) representation of environmental data, and (2) the interchange of environmental data sets.
To achieve these representation and interchange objectives, SEDRIS relies on its five core technology components. ...

4. The development of SEDRIS™ standards
|
Article by: Tim Gifford and Paul Foley
Role of standards in infrastructure technologies
Having a standard way to accomplish something considered an infrastructure technology serves two very useful roles. One, it frees the user to concentrate on the more important application-level development, since there is no need to devote time and resources to designing the infrastructure. Secondly, it makes it possible for the users to communicate effectively and unambiguously through a standard mechanism. This, in turn, makes interoperability possible.
Another important role of standards, and particularly international standards, is to subject the technology to scrutiny by a wider, more diverse audience. ...

5. Creating Environmental Databases for Use in Realtime Networked Interactive Simulation
|
Article by: Farid Mamaghani
ABSTRACT
Generating and representing environmental databases is a key factor in networked simulation systems. It’s particularly demanding to create an environment that looks good when traversed at ground level, instead of at 30,000 feet in a flight simulator. Realtime networked simulation places additional constraints on the successful creation of these environments. ...

6. SEDRIS™ : In-Use Today Supporting Interoperability and Reuse
|
Article by: Paul Foley
SEDRIS technology is serving the modeling and simulation (M&S) marketplace today. As SEDRIS technology progresses toward adoption as international information technology standards, many Department of Defense (DoD) and international users are adapting current and future system designs to benefit from SEDRIS’ complete and unambiguous representation of the physical environment....

7. Why SEDRIS™ : The Gap that Sedris Fills
|
Article by: Farid Mamaghani
TRENDS IMPACTING ENVRIONMENTAL DATA
The cost to acquire, tailor, and use environmental data will decrease as the information technology market’s reliance on environmental data and its needs to use and share such data increases....

8. What if SEDRIS™ Doesn't Meet My Needs?
|
Article by: Tim Gifford, Farid Mamaghani
ROOM FOR IMPROVEMENT
SEDRIS is designed to support the full spectrum of environmental data, as used by a wide range of applications. For the past few years the underlying technology has been used in a variety of programs and applications. And more than twenty organizations have seriously scrutinized the technology from a variety of different and diverse application perspectives. Many interchange experiments, all using real-world data sets, have been conducted. And today many U.S. and international projects, commercial organizations, and government programs are using SEDRIS in their application areas....

9. Using SEDRIS™ in your applications
|
Article by: Farid Mamaghani
Since SEDRIS is about representation and interchange of environmental data, its conceptual technologies can be applied to a diverse set of modeling tasks, while its software capabilities can be used in a variety of applications.
The SEDRIS Data Representation Model (SDRM) has a powerful and expressive schema for capturing and representing environmental data. The concepts and architecture of the SDRM have proven instrumental in developing system-level designs in a number of government projects, as well as industry products. Several commercial organizations have used the concepts and schema from SEDRIS in development of their next generation environmental tools, or in extending their current tool sets....

10. Application of SEDRIS™ in non-modeling & simulation (M&S) domains
|
Article by: Farid Mamaghani
As 3D and 4D representations of environmental data take root in other communities, we can expect an increased realization that the requirements for data representation and interchange are quite similar to those the M&S community has experienced for years. ...
