Building a 2.5D Digital Elevation Model from 2D Imagery [PDF]

When projecting imagery into a georeferenced coordinate frame, one needs to have some model of the geographical region that is being projected to. This model can sometimes be a simple geometrical curve, such as an ellipse or even a plane.
