VolksNav in USA: starting with urban radius r100

The definition of the radius r100 allows to build location codes which are smarter than post codes. They look like this example:

  StatusQuo City m4:7 r22  

This target could be a building, a crossing, a stop point, a bridge etc. The conventions for this format with hours, minutes and radius are as follows:

StatusQuo
prefix of a location code

Bases on a relevant point called r0, the urban pole.

Example: the Hollywood sign in L. A.

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.
