I recently surveyed a number of GCPs and the elevation is showing as negative. I’ve found a few other posts about this topic but I cant figure out the solution. I’ve used this same workflow/setup before any my elevations have been fine.
My understanding so far is that the Elevations are WGS84 ellipsoid and I have to convert them? I tried using this tool to convert but the elevations are still showing negative value. https://vdatum.noaa.gov/vdatumweb/
I dont understand why I’m getting this now as the projects I have done in the past, I just used the .csv export and it worked fine. How do I get these to the right elevations? I only need relative accuracy in state plane U.S. feet.
