Geoid heights and tiled model
« on: September 30, 2021, 12:42:37 PM »
In Metashape 1.74, when I work with a custom fixed height geoid and then export a tiled model and don't change the coordinate system, the output is ellipsoidal heights.

Hello Dieter,

Current version of Agisoft Viewer doesn't support coordinate system selection (including compound coordinate systems), so it shows height above ellipsoid.

At the same time TLS model stores the geocentric altitude data without any relation to the geoid model used in Metashape project.

Thanks for the answer.

However, this does not help me, because our customers also want the correct height (geoid) in the tiled model. Is there a workaround?



Just by the way: Why is the choice of a coordinate system offered when I export the tiled model if this selection is not taken into account anyway?
