The Aerial Survey Data Base(ASDB) is a data bank of photogrammetric control points that have been established through the process of aerotriangulation. The primary purpose of this data base is to provide a minimum of 4 points for the compilation of each photogrammetric model contained in a 1/50 000 National Topographic System(NTS) map sheet.  1, record 1, English, - Aerial%20Survey%20Data%20Base

Aerial triangulation, or aerotriangulation, is the process of determining X, Y, and Z ground coordinates of individual points based on measurements from photographs. Aerial triangulation is used extensively for many purposes.  3, record 7, English, - aerotriangulation

bridging :... densifying ground control through strips or a block of photos to be used in subsequent photogrammetric operations. When [aerotriangulation is] used for this purpose it is often called bridging, because it allows the computation of necessary control points between those measured in the field.  3, record 7, English, - aerotriangulation

Several programs have been developed for the adjustment of aerotriangulation measurements. Programs which adjust the entire block of photographs simultaneously are more rigourous & provide greater accuracy than programs using approximate or sequential methods. Recent progress has been made in the development of an adjustment program which compensates for factors such as non-uniform film deformation, departures from flatness of camera platen, & changes in lens distortion. This method is known as the bundle adjustment method with self-calibration.  1, record 11, English, - bundle%20adjustment
