Constraints

Example(s)

  • A producer’s image generator is configured to understand the local (origin offset from the UTM zone origin) UTM Augmented (Z added) SRF in which the database is built. However, the producer stored the data in the transmittal in the UTM Augmented SRF with the local offset removed.

    For purposes of comparison, the consumer would like to know the offset used in the original database development. This is so the producer can do direct comparisons of the producer and consumer systems using their respective image generators.
