Environmental Domain Summary

Class Name: Environmental Domain Summary

Superclass - <SEDRIS Abstract Base>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class summarizes a single environmental domain (such as terrain, ocean, atmosphere) to which at least part of the data set described by its aggregate <Transmittal Summary> relates.

The complete list of < Environmental Domain Summary> components of a <Transmittal Summary> summarizes the total coverage of the transmittal being described.

This class appears on only one page of the DRM class diagram.

Example

  1. Consider a transmittal containing a polygonal representation of a terrain skin. It consequently contains an <Environmental Domain Summary> with environmental_domain = ECC_LAND.

  2. Consider a transmittal containing a < Property Grid> of sound speed ( EAC_WATER_BODY_SOUND_SPEED) versus depth in water.

    The transmittal consequently contains an <Environmental Domain Summary> with environmental_domain = ECC_WATER_BODY_ACOUSTIC_PROPERTY_SET.

  3. A transmittal containing <Property Grid> instances of terrain heights and ocean floor depths consequently has two <Environmental Domain Summary> instances with environmental_domain = ECC_LAND and environmental_domain = ECC_OCEAN_FLOOR, respectively.
