VolksNav(c) in Douala

Click or doubleClick a point on map to know the logical indoor or urban address of that point

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 circle shows r100 = 10km.

The division of the horizon into 12 directions can also be used global or indoor.

The map above converts lat/lon to StatusQuo(c) on a simplified mode, tolerable for radius < 10 km. For a professional conversion, see VolksNav.com/mapplet and the following site:

The Munich Orientation Convention bases on imaginary clocks, a method used by soldiers, boy scouts, blind people, pilots etc. for more than 100 years.

This convention quantifies positions in harmony with imagination power, cartography, modern post codes, search engines, navigation devices and codes for crossings, stations, bus stops, bridges etc.

The search grid is a quasipolar one, is scalable and has other innovative characteristics, see Magic Grid. The index on map is at the same time an intelligent postal code on reality!

See on sector m7 is a typical quad 5 x 5km, blue filled. The bended sides let you know the direction or the urban pole even if the pole is outside of the map.

VolksNav(c): special pictograms on signage and navigation devices let detect the directions north and indoor/urban/global pole. The user will be able to guide himself as elegantly as in Rio de Janeiro around the Christ statue: inwards/outwards and clockwise/counter clockwise.

Exercise: just using your brain, try to imagine the following route: m1 r40 to m5 r90
