Superclass - <SEDRIS Abstract Base>

Subclasses

Definition

An instance of this DRM class is the hierarchical root of all DRM class instances in a single SEDRIS transmittal. As such, it is the basic unit of interchange. The content of a transmittal can be as simple as a single <Model> instance, or as complex as a complete representation of a large geographic region with all the <Model> instances, terrain, atmospheric, and oceanographic data necessary to simulate an environment.
