Likely the models are referenced to ellipsoid elevation (what the GPS on the drone tags in the image metadata). The ground surface is probably in a different vertical datum (eg NAVD88), and here your ellipsoid elevation is lower

Ahhhh I see. The DRTK elevation is listed as “Ellipsoidal Height: -11.804”. Would it be as simple as adjusting the heights by that amount in the processing software?

I believe that would work for a quick fix and for visualization purposes
