Document Summary

Photo or image interpretation is defined as the examination of images for the purpose of identifying objects and their significance. A vertical or oblique aerial photograph or other type of visible/near infrared image records a detailed but much reduced version of reality. Examination of the earth from an aerial perspective allows scientists and the general public to identify objects, patterns, and human land interrelationships that may never be completely understood if we were constrained to a earth bound vantage point. Humans are accustomed to looking at the facade or side of objects and do not normally have an appreciation for what objects look like when they are recorded from a vertical view. Possible to obtain a 3d view of terrain as if were were actually airborne. One way is to abstain two images from two slightly different vantage points. Our eyes are sensitive to primarily blue, green and red light.
