Class

• <DRM SRF Summary>

Superclass

• <DRM SEDRIS Abstract Base>

Subclass

• None.

Definition

An instance of this DRM class specifies that the SRF identified by the srf_context_info field is used by at least one instance of the DRM class being summarized by the aggregating <DRM DRM Class Summary Item> instance.

The srf_context_info field specifies the SRF being identified.

Constraints

• Non-overlapping <DRM DRM Class Summary Item> instances
• Publishable object

Example(s)

• Consider a transmittal containing terrain geometry, an oceanographic <DRM Property Grid> instance, an atmospheric <DRM Property Grid> instance, and a number of <DRM Model> instances. The terrain is in one SRF, the oceanographic <DRM Property Grid> instance in another, the atmospheric <DRM Property Grid> instance in a third, and some of the <DRM Model> instances in a fourth (in this example, LSR). This situation can be summarized as depicted in Figure 6.324 where appropriate <DRM SRF Summary> instances are components of the respective <DRM DRM Class Summary Item> instances.

  

  Figure 6.324 — <DRM SRF Summary> example

• Consider a transmittal in which the environment being represented covers two adjacent cells in GTRS Global Coordinate System SRFs. The data provider represents this by creating a <DRM Transmittal Root> instance with two <DRM Environment Root> components, one for each GTRS GCS SRF.
