"Photogrammetry, especially aerial photogrammetry, has been accepted by the mining industry as an important tool for surveying of large open pits, for the updating of pit plans, calculation of mined volumes, estimation of mass movements, and the provision of topographical maps. Terrestrial photogrammetry can be used to obtain geological information on orientation, spacing and length of joints from steep rock slopes with limited access. This supplement, in serving as a guide to principles, accuracy, data collection, analysis and costs, is intended to encourage the use of terrestrial photogrammetry to its full potential. It will assist geologists in assessing the applicability of the technique to their objectives and will familiarize photogrammetric analysts with some aspects of geological discontinuity observation"--Summary.
