VolksNav in Nigeria: starting with urban radius r100

Location codes for targets, crossings, stop points, bridges etc. look like this:

StatusQuo Abuja m4:7 r22

The conventions for this format with hours, minutes and radius are as follows:

StatusQuo(c)	prefix of a location code	Bases on an relevant point (urban pole) called m0 or r0. Example Abuja: main crossing
m12	basic horizon hour	This is the direction from urban pole to north. m3 will be to east, m6 to south etc. This method divides the city like a cake into 12 sectors.
number after the " : "	horizon minutes	distance to the horizon hour, in steps of 100 meters.
r...	radius	This is the distance to the pole, in steps of 100m. The small red circles show "CityName r100" = 10km radius.
