Since the publication of the first edition in the 1940s, the Manual of Photogrammetry has served as the comprehensive reference for those working in the field of photogrammetry and for those in other fields who need to use or understand photogrammetric applications. Recent years have seen fundamental changes in photogrammetric theory and practice, due both to technological changes such as the the widespread adoption of digital imagery, and also the emergence of separate fields with strong photogrammetric components, such as geographic information systems, computer vision and remote sensing. The Sixth Edition of the Manual covers photogrammetry in depth, as well as its constituent technologies, providing the student, practitioner or researcher with a single valuable reference resource.
