In this paper, an analytical photogrammetric evaluation system, developed using off- the-shelf optical, mechanical and electronical components, will be introduced. The measurement of the diapositive (up to the format 24 x 24 cm') is based on two low- priced, hut precise x, y-positioning systems, driven by step motors via spindles. Stage positioning in comparator or model mode is provided by two trackballs. The software contains a special program for 3D representation of buildings. This paper reports on the possible increase in efficiency by using high resolution photography.
