Digital Elevation Model (DEM) validation is often carried out by comparing the data with a set of ground control points. However, the quality of a DEM can also be considered in terms of shape realism.

What Happened: So, it looks like Apple is working on some wild new satellite features for the iPhone that go way beyond just sending an SOS text. What’s Next: Here’s the big question: Apple currently ...
