Marker elevation different in DEM file. - what can cause this ?
« on: January 10, 2015, 04:06:54 PM »
I am stuck at a project.
Markers are added with precise elevation, And all good ones are enabled(checkbox next to marker)
They match photos just fine, but when I export a geotif, all elevations are off by several meters.
Even a marker point is 29.076m instead of 35.835 meter.  (this goes for all markers.)

Did you optimize the model on the markers?

First disable all the camera positions by selecting them all and right click > uncheck.

Then go to the reference control pane and set the marker accuracy to 0.001m (1mm) and then optimize the model with the optimization tool with all the markers checked.
