Geoid Not Being Applied

[Shovelhead]

I have images that were captured in WGS84 (RTK) and I would like to convert them to NAD83 UTM11N with a CGVD23 (HTv2.0 Geoid).

When I choose convert to "NAD83(CSRS) / UTM zone 11N" I can see there is no vertical datum applied to that map projection. I have the option to convert to  "NAD83(CSRS) / UTM zone 11N + CGVD2013 height" but we don't really use CGVD2013 here.

I tried that option anyways knowing my local shift is 0.30m and it came it 0.60m out of position so something weird is going on there too.

I can shift my finished point cloud in NAD83(CSRS) / UTM zone 11N by the CGVD28 geoid separation in CloudCompare and it works out ok but its not really the right way to do it because I'm shifting ellipsoid elevations. On this site the geoid separation changes by about 30mm from one end to the other.

My current work around was to shift the CGVD2013 converted cloud. It's still not right but the best I have right now. The geoids match up relatively well over small areas.

Does anyone know how I can apply the Geoid I want to apply? I have it in my Geoid folder already, I just need to figure out how I can apply it. Ideally I could tell Agisoft that X geoid should belong to Y map projection.

Hello,

you can just follow the following from knowledge base https://agisoft.freshdesk.com/support/solutions/articles/31000148332-how-to-use-height-above-geoid-for-the-coordinate-system

In following screen shot, I show how I edited the CS adding CGVD28 height and in Vertical CS choose Custom and in Edit Vertical CS choose Canadian Geodetic Vertical Datum of 1928 and it should work,,,,

Im running an older version that doesn't have that feature. I can make my own prj file and use that if I can see an example of how other prj files are loading their geoids. Does Agisoft store that information anywhere in the file structure where I can go and view it?
