The procedure aims to enhance the contrast of image in order to improve the interpretation.

A set of reference points with known coordinates/positions of high order (high degree of accuracy and precision).

A reference point precisely located on the ground as well as the image (ground control point) or on both a map and the photo (map control point), or on two adjacent photos (photo control point)

Ground control, with known location (coordinates), used to monitor/track satellites; collects information regarding path of satellite, calculates atmospheric error and perform clock correction for satellite.

Angle measured from the meridian (true north) to a vertical grid line (grid north).

Map Generalization techique, changing map elements from an irregular shape to representative points/lines.

Lens that focus light beam to a single point, distance from the lens to focus point is the Focal Length (commonly denoted by f).

A mathematical operation on two functions , producing a third function that is typically viewed as a modified version of one of the original functions, giving the area overlap between the two functions.
