CONT: 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.
OBS: 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.
