dc.description.abstract | The CDB standard defines a standardized model and structure for a single, versionable, virtual
representation of the earth. A CDB structured data store provides for a geospatial content and
model definition repository that is plug-and-play interoperable between database authoring
workstations. Moreover, a CDB structured data store can be used as a common online (or
runtime) repository from which various simulator client-devices can simultaneously retrieve and
modify, in real-time, relevant information to perform their respective runtime simulation tasks.
In this case, a CDB is plug-and-play interoperable between CDB-compliant simulators. A CDB
can be readily used by existing simulation client-devices (legacy Image Generators, Radar
simulator, Computer Generated Forces, etc.) through a data publishing process that is performed
on-demand in real-time.
The application of CDB to future simulation architectures will significantly reduce runtimesource
level and algorithmic correlation errors, while reducing development, update and
configuration management timelines. With the addition of the High Level Architecture - -
Federation Object Model (HLA/FOM)1 and DIS protocols, the application of the CDB standard
provides a Common Environment to which inter-connected simulators share a common view of
the simulated environment.
The CDB standard defines an open format for the storage, access and modification of a synthetic
environment database. A synthetic environment is a computer simulation that represents
activities at a high level of realism, from simulation of theaters of war to factories and
manufacturing processes. These environments may be created within a single computer or a vast
distributed network connected by local and wide area networks and augmented by super-realistic
special effects and accurate behavioral models. SE allows visualization of and immersion into
the environment being simulated2.
This standard defines the organization and storage structure of a worldwide synthetic
representation of the earth as well as the conventions necessary to support all of the subsystems
of a full-mission simulator. The standard makes use of several commercial and simulation data
formats endorsed by leaders of the database tools industry. A series of associated OGC Best
Practice documents define rules and guidelines for data representation of real world features.
The CDB synthetic environment is a representation of the natural environment including external
features such as man-made structures and systems. A CDB data store can include terrain relief,
terrain imagery, three-dimensional (3D) models of natural and man-made cultural features, 3D
models of dynamic vehicles, the ocean surface, and the ocean bottom, including features (both natural and man-made) on the ocean floor. In addition, the data store can includes the specific
attributes of the synthetic environment data as well as their relationships.
The associated CDB Standard Best Practice documents provide a description of a data schema
for Synthetic Environmental information (i.e. it merely describes data) for use in simulation.
The CDB Standard provides a rigorous definition of the semantic meaning for each dataset, each
attribute and establishes the structure/organization of that data as a schema comprised of a folder
hierarchy and files with internal (industry-standard) formats.
A CDB conformant data store contains datasets organized in layers, tiles and levels-of-detail.
Together, these datasets represent the features of a synthetic environment for the purposes of
distributed simulation applications. The organization of the synthetic environmental data in a
CDB compliant data store is specifically tailored for real-time applications. | en_US |
