Class Name: Reference Origin

Superclass - SEDRIS Abstract Base

Definition

A location that specifies the origin in which the data was originally modeled. This location is intended to convey information about how the original data was represented on the producer system (before the data was transformed into a SEDRIS approved reference frame).

Example

  1. A producer's image generator is configured to understand the Local (origin offset from the UTM zone origin) Augmented (Z added) UTM reference frame the database is built in. However, the producer stored the data in SEDRIS in the Augmented UTM reference frame 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.

FAQs

Is the Reference Origin needed to properly locate the data?

What would the Reference Origin be used for?
Correlation of data between consumer and producer.
