OCAD (Orienteering Computer Aided Design) is a software system for cartography (map making) with particular functionality for use connected to the sport of orienteering, which involves direction-finding. The software was created in Switzerland and released in 17 languages. It is sold on a subscription basis.

Identification

Files start with the bytes AD 0C (hex), which represent a 16-bit integer 0CAD (hex) in little-endian form, spelling out the name of the software. (It's equivalent to the less interesting 3245 in decimal.) The specs don't specifically mention the endianness, so it's possible that implementations on system architectures with big-endian system-level order might start files with 0C AD and produce files not necessarily compatible with other systems, though it does not appear that such implementations actually exist.

The following byte is 0 for a normal map, 1 for a course setting project, 2 for a file saved in Server.
