UK Photogrammetry is the Science of determining spatial data from photographs.
Precision is flexible and commensurate with scale.
This has freed the type of usable photography from most of the geometric constraints enforced by mechanical and optical limitations of early plotting instruments. Furthermore, such imagery can be acquired using a wide range of photographic cameras, including conventional 35mm cameras. The parallel development of silicon based technologies have provided the foundation of the logical extension to analytical methods, digital photogrammetry . The use of 3D Computer Aided Design packages to manipulate and store measured 3D coordinates has provided photogrammetrists with a powerful tool and a means to enter new markets. The increasing need to manage that most basic resource, space, requires tools to develop 3D CAD models of existing structures and terrain.
