Definition

A <DRM 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 <DRM Model>, or as complex as a complete representation of a large geographic area with all of the <DRM Model>s, terrain, atmospheric, and oceanographic data necessary to simulate an environment.

Example(s)

·         SIMNET databases such as Grafenfels and Ft. Knox.
