Example

Consider environmental data representing a transmittal containing a polygonal terrain representation that was derived from a DTED representation. The <Lineage> instance for the <Transmittal Root> instance of this example transmittal might have a <Process Step> component describing the polygonalization process as well as a <Source> component corresponding to the DTED representation.
