errors in Publication 229

[alan2]

I believe that this likely has been mentioed before, however for what it might be worth, I understand that some errors have been found in on-line versions of Publication 229, formerly HO 229.

Regarding Publication 229 that one finds on-line, have these errors been corrected in current versions?

I’m unaware of any errors that would be unique to the on-line version of Publication 229.
The version available at the NGA website are PDF images of the printed version.
