Andy: Hardly wrong at all, maybe a matter of how I phrased it, maybe I should have left out the word "meridian". Yes, the meridians do converge (get c...

Convergence of the meridians has nothing to do with any grid system. The convergence angle is what you describe as between grid north and geodetic nor...

to answer your original question, there is no "add-on" (geoid model) available to go from GRS80 ellipsoidal heights to NGVD29.

In order to use NGVD29 you would need to tie at least one NGVD29 benchmark (i.e. marks with PUBLISHED NGVD29 values). Four surrounding your project wo...

Because when you move east or west there is convergence of the meridians. If you have two points several miles apart on the same latitude the differen...

I have found with TBC there is not a lot you can do. In the older processors I would raise the elevation mask to 15 and then 18.
