When orienteering competitions first took place, the customary topographic maps were sufficient for organising orienteering events. Beginning in the sixties, the existing map series were updated in order to represent the terrain in more detail. Map scales of 1:15,000 or 1:10,000 with an equidistance of 5 metres have proven to be ideal. Because such maps are not available on the market, orienteering organisations must produce these themselves. Existing map series are enhanced with additional features according to internationally valid display regulations for orienteering maps. Survey plans and interpretations of aerial photographs are used as a base. Map objects are mostly recorded in a map sketch with the help of a compass and the number of foot steps or with distance measuring equipment. These various map sketches were combined to a complete base map. In a next step the map features had to be drawn in separate colours with rapidographs on polyester film.
At the beginning of the nineties, OCAD was founded with the goal of producing a drafting software for facilitating the handling of the core production process of orienteering maps – from drawing map sketches to the output of film positives for printing. In addition, the software had to be easy to learn and cost-efficient. This was a necessity because the volunteers who mapped the terrain and drew the orienteering maps could not afford expensive software, hardware or introduction courses.
