At the same time as practical and technological developments and mutual impact in raising the quality and scientific potential of surveying services, manufacturers of technical devices and equipment also struggle day by day to present new achievements. Over the past three years, with the exit of analogue photogrammetric devices from the market and their replacement with analytical devices, there has been a remarkable transformation in the field of surveying and utilization of computer in that field, and extraordinary progress can be witnessed every day in the field of small and large analytical devices that use microcomputers. What’s more, a series of modern photogrammetric devices are introduced into market by manufacturers that have often had no connection with photogrammetry and mapping in the past. There are many innovative ideas available on these small but powerful devices many of which have applied aspects in the fields of photogrammetry, preparation of thematic maps and revision of previously made maps. Another valuable innovation and initiative which should be mentioned is conversion systems for the purpose of an appropriate transformation of analogous photogrammetric devices into analytical ones.
