(answers appear at the bottom of
the page)
The following is a list of questions that were assembled to test your
knowledge of the matertial presented throughout the About
SEDRIS section.
Question 1: Which of the following is not one of the five SEDRIS
core technology components?
- a. SEDRIS Data Representation Model (DRM)
- b. SEDRIS Transmittal Format (STF)
- c. the Terrain Data Coding Specification (TDCS)
- d. the SEDRIS interface specification (API)
Question 2: Which of the following statements is not true regarding
the Environmental Data Coding Specification (EDCS)?
- a. The EDCS is designed such that it can be utilized independently
of the SEDRIS Data Representation Model (DRM).
- b. Conventions for ocean, atmosphere, and space domains are
based on the classification and attribute codes from the standards of those
domains.
- c. The EDCS convention has been designed to enable the inclusion
of additional codes.
- d. The EDCS provides for conventions in classifying objects,
while allowing individual developers to include their own convention for
describing object attributes.

Question 4: Which of the following statements accurately describes
the relationship between interoperability and interchange?
- a. the terms "interoperability" and "interchange"
are synonymous
- b. interchange refers to the exchange of data, while interoperability
refers to the common understanding of the exchanged data
- c. simulation systems interoperate through an interchange mechanism
- d. interoperability refers to the exchange of data, while interchange
refers to the common understanding of the exchanged data
Question 5: SEDRIS is a ________________.
- a. proprietary open-standard for sharing environmental databases.
- b. non-proprietary tool for sharing environmental databases.
- c. non-proprietary open-standard for simulation interoperability.
- d. non-proprietary open-standard for sharing environmental databases.
Question 6: What are the two key aspects of SEDRIS?
- a. representation of environmental data and the interchange
of environmental data sets
- b. standardization of environmental data sets and interoperability
among simulations
- c. developing new techniques for modeling terrain and interchange
of environmental data sets
- d. representation of environmental data and the development
of homogeneous data types
Question 7: Which of the following statements is true?
- a. SEDRIS is a Department of Defense policy regarding the use
of environmental data in simulations.
- b. SEDRIS provides a unifying mechanism for sharing environmental
data.
- c. SEDRIS is an authoring tool for creating environmental databases.
- d. A developer must be SEDRIS certified in order to access SEDRIS
data.
Question 8: What does "integrated environmental data"
mean?
- a. environmental databases that were developed by a diverse
team
- b. environmental data that is developed through common tools
within an industry or government organization
- c. environmental data that is a coherent fusion of separate
data sets and describes a region
- d. the collection of several independent environmental databases
into a single transmittal
Question 9: Which of the following is true?
Question 10: The underlying data that can describe the terrain
surface is often called the:
- a. SEDRIS root database.
- b. digital elevation model (DEM).
- c. polygonal framework model (PFM).
- d. environmental database groundwork.
Question 11: Why are textures used in environmental modeling?
- a. Textures add substantial detail to the visual representation
that is not achievable with simple geometry alone.
- b. Textures enable the environment to be perceived haptically.
- c. Textures are required by IEEE 1248.11.
- d. b & c
Question 12: Which of the following is not a recommended step
for making an environmental database?
