VolksNav in Holland: 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(c) 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(c) |
prefix of a location code | Bases on a relevant point called m0 or r0, the urban pole. Example : |
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 big red circle shows r100 km around Den Haag for National Codes. |
