The convention for urban position codes is:
| StatusQuo(c) Douala | prefix of a position code | The urban pole is the Place de l'Independence |
| m12 | basic horizon hour | from urban pole to north, m3 to east etc. |
| number after the " : " | horizon minutes | distance to the horizon hour, in steps of 100 meters The blue lines on grid show :50 minutes |
| r... | radius |
distance to the urban pole, in steps of 100m. The red circles show r100 = 10 km.and r20 = 2 km |
This map converts lat/lon to StatusQuo(c) on a simplified mode, tolerable for radius < 10 km. For a professional conversion, see VolksNav.com/mapplet
For example, codes for points-of-decision could complement the actual signage, which also can indicate the directions north (red) and city pole (yellow).
The division of the horizon into 12 directions can also be used global or indoor, example Douala Grand Mall
. 1 unity = 1 meter
