Abstract

Before computers and photogrammetry related image processing programs much of the work of extracting information from aerial photographs was done by hand. Here are several very basic methods for finding out such things as the elevation above base of vertical objects, determining area of an irregular subject, determining area by graphical means and height of objects based on shadow. Added here in April 2007.
