The role of close range photogrammetry (CRP) in engineering geology is described, the relative advantages and limitations of the technique being outlined. A comprehensive literature review reports on the use of CRP for in situ monitoring of earth and rockfill dams, retaining walls, rockfaces and landslides, channel and gully erosion and, also, laboratory based experiments. The historical development of analytical CRP and the types of project where such a technique would be appropriate are subsequently discussed. Two case histories illustrating the use of analytical CRP for monitoring a series of eroded slopes in southern England are reported. The paper also examines the benefits which occur when digital photogrammetric data of this type are integrated with suitable ground modelling software.
