An aside to this issue: the NIMA pdf Janne ref'ed on local geodetic systems
notes "ID codes" with it appendix of ellipoid tables. For example: WGS 84
was code "WE".
Reference may be in the pdf but I could not locate it. It just refers
to "standardized two letter code."
Does anyone know where and who is responsible for these codes?

The whole religious complexion of the modern world is due
