Abstract : Orthophoto maps as basic mapping components are being accepted by many national mapping agencies. There are also competent experts, both in the map production field and in the instrument manufacturing industry, who predict that photomaps will soon take the place of conventional maps out of necessity. Apparently, in some countries, there is already a lack of draftsmen for drawing conventional maps. Even if these predictions should be exaggerated there is a need for a selfcontained logically designed orthophoto system which will not only comprise facilities for the production of orthophotos, but also efficient and simple means to convert these orthophotos into orthophoto maps and to update these maps.
