Every GEOCODEs try to be simple and short. But purpose is vary.
Some GEOCODEs are designed for computer usage only, and others are designed for human usage. For human use, code must be “readable coordinates” and should be reflected to printed map, intuitively.
NAC, LocaPoint, LP-Address, N-Code have a code format that have latitude part and longitude part, separately. It gives intuitive interface like guide maps. I have to mention that N-Code use only numbers in purpose of children’s use.
Munich Orientation Convention (StatusQuo) has unique intuitive interface. It uses polar-style coordinates, like orientation methods. Unlike other code has Guide Map style (X-Y style) guidance, StatusQuo provide angle in time format (3:00 for East, 6:00 for South, etc) and distance from origin point that is defined for each city. If city structure is not X-Y shape, and is polar shape like Rio de Janeiro or Paris, StatusQuo Code follows city road structure and more intuitive. StatusQuo is designed for illiterate or children who can only read numbers and clock in developing countries.

Non-intuitive GEOCODES are not designed for human handling. It is very difficult to handle for human. Instead, it can be more “compressed” and shorter. For example, SONY’s code is made through bit operation, and human can’t tell where the code shows directly. Similarly, GeoPo try to make code as short as possible, because GeoPo is designed for Twitter usage and try to save character length due to Twitter’s length limit.
