Class Name: Transmittal Root

Superclass - SEDRIS Abstract Base

Definition

A Transmittal Root is the hierarchical root of all objects in a single SEDRIS transmittal. As such it is the basic unit of interchange. It can be as simple as a single Model, or as complex as a complete representation of a large geographic area with all of the Models, terrain, atmospheric, and oceanographic data necessary to simulate an environment.
