Quote:quotehotogrammetry is the technique of measuring from photographs. A three-dimensional optical model is constructed from two photographs and can be accurately measured on a measuring instrument to give either graphical or digital results. Alternatively, a great deal of information can be obtained just by viewing the subject in three dimensions, and the photographs can be measured using simple graphical techniques, though with a much lower level of accuracy. The main advantage to the archaeologist in using photogrammetry lies in the speed of on-site recording and the vast amount of detail that can be retrieved from the images. Photogrammetry is also useful when the subject is either fragile or inaccessible, since it involves no contact with the subject. The main disadvantages are the cost of using expensive instrumentation and the delay in obtaining the results after the photography has been completed. When archaeologists use photogrammetry, they should work in close cooperation with a professional photogrammetrist.
