Good day,
I'm hoping that maybe someone out there may be able to help me with these
questions.
What is the difference between a DEM and a DTM?
Is a DTM preferred for the ortho-rectification of aerial imagery and why?
Is LYDAR the preferred method for the development of a DTM and are there
other less expensive ways to do this?
Thanks so much for any help you all may give me.
I will sum.
Thanks,
Jeff Boudrie
