Example(s)

  • A producer’s image generator is configured to understand 3D coordinates in the local (origin offset from the UTM zone origin) UTM SRF in which the environmental data is specified. However, the producer represented the data in a transmittal in the UTM SRF with the local offset removed.

    For purposes of comparison, the consumer wants to know the offset used in the original database development. This allows direct comparison of the producer and consumer systems using the respective image generators.
