Photo Interpretation: The examination of aerial photographs/images for the purpose of identifying objects and judging their significance. Observation & Inference: Observation provides the raw data for interpretation. Inference is the logical process by which observation and interpretation are made Aerial photography is defined as the science of making photographs from the air for the study of the surface of the earth. Aerial photographs are taken from airplanes by special cameras. There is about 55% to 70% front overlap in between two successive aerial photography because of this it is possible to obtain a three-dimensional picture of. Air photo coverage is generally designed to provide about 60% forward overlap between photographs. This allows stereoscopic, or 3D, viewing when the two overlapping photos are used with a stereoscope. In addition, from 20 to 40% lateral (side) overlap is allowed when complete coverage of an area is required In aerial photography, when two photographs overlap or the same ground area is photographed from two separate position forms a stereo-pair, used for three dimension viewing. Thus obtained a pair of stereoscopic photographs or images can be viewed 26

Aerial photography is an important source not just for researchers but also at events, parties and film production. Flying a drone above the head requires special skills of handling and also certain codes to avoid intruder case filings Aerial photography is a pattern pf photography from a platform to take photographs of the earth surface and features found on it. The early form of aerial photography was through balloon, kite, birds (pigeon) and later, aircraft was introduced in 1909 by the Wright brothers. Aerial photography has a basic element which is the electromagnetic.

Aerial Photography and Planes. A history of aerial photography wouldn't be complete without looking at the work of photographers and pilots in planes. The rise of fast, effective aircraft and personal planes gave photographers more opportunity to head into the clouds and capture images of the scenes below The two main advantages of aerial photography over space imagery are 1) the mission can be flown at any time, weather permitting, and 2) resolution is usually higher (although recent Russian and American commercial products from space are narrowing that gap). Examples of aerial photos of different scales and types are shown Principles of Photogrammetry Lecture 5: Introduction to Photogrammetry Characteristics aerial photography Marginal data of aerial photography Fiducialmarks:smallregistration marksexposedontheedgesofa photograph.Thedistancesbetween fiducial marks are precisely measured when a camera is calibrated.

26 Principles of Remote Sensing During early half of twentieth century, aerial photos were used in military surveys and topographical mapping. Main advantage of aerial photos has been the high spatial resolution with fine details and therefore they are still used for mapping at large scale such as in route surveys, town planning By making these assumptions, the aerial photograph is a graphic record of the light rays or, in mathematical terms, a presentation of the relationship between the aerial camera and the ground. Thus, for a truly vertical photograph (Figure below) , the geometry of the relationship can be expressed a

Aerial photo interpretation: Aerial photo interpretation is a method of studying terrain by examining aerial photographs of it, involving detection and identification of the objects photographed, determination of their qualitative and quantitative characteristics, and recording the results graphically (using standard symbols), numerically, and. aerial photographs showing deer, for example, as they would appear to ob-servers in making an aerial census.
