Visual DTM Alignment for DEM Export

[tdepke]

I have two models of the same area (riverbank) that were created at two different time periods. I want to try and measure the difference between these two models, however, my surveyed coordinates were a few feet off, which causes models to be really of when exporting them as DEMs. Would there be a way so that you could view two DTMs in the same visual space, move them both around, and export them as DEMs? There are enough similarities in the models that a visual overlap would be sufficient, but I cannot figure out a good way to do this.

Thanks,

Tyler

Hello Tyler,

I think that you can try to align the chunks containing these two models. If the alignment is successful the reference between chunks could be better then you have with GCPs.
But if the difference between models is too big it wouldn't work if chunks are being aligned based on points.
