The use of overlapping parts of stereo photography is a long established and very accurate method for the production of 3D datasets. Modern software enables rapid processing of the data to give end deliverables that are analogous to laser scan pointclouds.
Photogrammetric surveys are much slower than laser scanning, however may be used in certain situations such as: the need for extreme detail on a particular feature (e.g. heritage buildings), infill of shadow zones where scan data could not be acquired and where the highest true to life representation is required. Photogrammetric data can be easily integrated with other survey data, as can be seen towards the end of this illustrative video. [Bamburgh Castle]
