An alternative approach to manual interpretation of aerial photographs involves the application of analytical methods based on digital image processing Avery and Berlin 1992, Sonka et al. Utilizing an unmanned, remotely piloted vehicle, offers cost effective alternatives to traditional aerial photography. The Single Vertical Aerial Photograph The geometry of an aerial photograph is based on the simple, fundamental condition of collinearity. Aerial photography typically refers specifically to bird's-eye view images that focus on landscapes and surface objects, and should not be confused with air-to-air photography, where one or more aircraft are used as chase planes that "chase" and photograph other aircraft in flight. Aerial photographs give a bird’s eye view of large areas enabling us to see surface features in their spatial context. Aerial photos are now a must for a highway engineer for the planning , alignment and execution of highway project. Aerial photography is one of the oldest and simplest methods used in remote sensing to capture images of the Earth’s surface. Types of Aerial Photography Angle of Photo Aerial photographs may be taken in vertical, low-oblique or high-oblique positions. Classification of Photographs In his book on aerial photo interpretation, Paine presents a dichotomous key for classifying aerial photography. This allowed photographic interpreters to view aerial photographs in three dimensions. An aerial photograph is a photograph of the Earth's surface taken from an elevated or direct-down position, typically from an airplane, satellite, helicopter, balloon, or drone.
