Empty extent
« on: January 11, 2016, 09:14:31 PM »
If I try to generate an orthomosaic from the DEM of my project I get a "Empty extent" message after analyzing the DEM.
Generation from mesh works.
What is happening here?

Hello Mathias,

Is it possible that you have georeferenced the data using different information after DEM generation process?

Hello Alexey,
yes, I have converted the data in a different coordinate system.
Is this the reason for the empty extend?

Hello Mathias,

If you have referenced the model in another coordiante system after building DEM, you need to rebuild DEM, as it remain in the older projection, while the orthomosaic generation process is trying to find the surface in the new projection.
