dc.description.abstract | This document provides detailed implementation guidance for developing and
maintaining a CDB compliant data store.
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
runtime-source 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 manmade
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-ofdetail.
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 |
