Munich Orientation Convention in Chengdu   中文             OpenStreetMap           other cities

Chengdu has the option to be world's first city that has realized an international orientation standard, an idea from a Munichian inventor to simplify and harmonize worldwide all orientation means: signage, cartography, navigation devices and verbal expressions. 

Within this city, it is (will be) possible to find any target with easy brain work, that means 

- without maps, - without names,
- without illogical numbers  - without arrows
- without floor marks  - without square grids 
- without colors - without compass or other navigation devices

Buildings, crossings, stop points, bridges etc. have logical addresses like

              Hospital of Chengdu University of 

              Traditional Chinese Medicine     StatusQuo© CD  m10 r25

              World Trade Center                                              m1:2 r9

              German consulate                                                m5:15 r36

             Shuangku Changdu airport                                     m7:50 r140

which are easy to understand if you associate the city with a clock as follows:

An outstanding point, e. g. the Tianfu square, was (will be) defined as a pole m0. Around this pole, the horizon is divided in 12 "horizon hours"     

    m1  to  m12   , 

whereas m12 points to north.

Horizon hours are divided in horizon minutes. These are not angles but DISTANCES to the horizon hour, in steps of approx one "block of houses" or 100 meters. 

    Example      m3:10           

( read   "emm three point ten"   or   "emm three ten" ). 

This is a line situated in a distance of 10 x 100m from the horizon hour m3, which points to sunrise. The convention for horizon minutes is very easy:        

the greater, the later     

Considering the distance to m0 as r = radius also in steps of blocks of houses, logical position codes for targets, buildings, crossings etc. come into existence, e. g. as shown on the picture: 

        crossing   m5:10 r40

In simple words:

"r" is a numbering starting FROM m0

"m" is a north-direction-based numbering AROUND m0  

and this simple methode covers a gigantic market gap: 

      l o g i c a l   and easy understandable  p o s i t i o n   codes.


Natural Cartography©: 

a map with such a polar grid has innovative characteritics, see  Even if targets aren't on map, the logical position codes make it possible to imagine where they are situated ! 



StatusQuo© addresses will be integrated within the existing signage, see, or be indicated on so-called Orientators©, the signage of the future.

Vertical Pointing©: additional to the position information, a round symbol called center or pole pointer will be placed on their periphery to allow to detect the direction m0  according to the following conventions: 

if the pointer is placed on top m0 will be in front of you
  on bottom   behind
  right hand   right hand

etc. Acc. to the same convention, a square symbol points to north = m12.  The picture reveils: m12 is behind, the pole is right hand 



Navigation / VolksNav©:

The local navigation with the help of such codes is called VolksNav©. As proceeded today with house numbers, VolksNav© is nothing else than the major/minor comparison between "r" and "m" values: 

Simply proceed according to 1 -2 -3 : 





Turn your body until m0 will be BEHIND. In this position, 

ahead will be outwards
right hand " to later (clockwise)
left hand " to earlier


Beginners have to turn physically, after some exercises anyone will be able to do this by his imagination power. In case you look at above shown Orientator©, you'd have to turn to left, correct? 




Ask yourself:         

must I move inwards or outwards? 

 ( = is the target radius greater or smaller than the actual one?)




Ask yourself:      

must I move to “later” (clockwise) or to earlier?  

( = is the target m later or earlier than the actual one?)


Let's see an example: 

Your target is:                           German consulate      m5:15 r36       

If you've lost orientation on named crossing                 m5:10 r40

so you must go

- inwards (radius r36 is less than actual r40 )


- to later" (clockwise)   ( m5:15 is "later"  than the actual m5:10 )

This may seem to be unfamiliar, but the orientation based on cardinal points is used for some thousand years and imaginary clocks are used by soldiers, boy scouts, pilots, blind people etc. for more than 100 years. On a real situation, VolksNav© can be learned within few minutes, that means, faster than the most seeking times. 


Mobile applications: Very soon also navigation devices and mobile phones will indicate such logical position codes and cardinal points , see

You're invited to test the program for pocketPC/smartphone with/without GPS by means of a download from


Natural World Co-ordinates: the same addressing methode will soon also be used 

- indoor 


- within the whole globe, see Acc. to this, the international City Code of Chengdu is 

          WatchRose© m2:710  r77 00      

What is this good for? Just comparing the codes for example of Chengdu and  

          Xindu  WatchRose©  m2:690  r76 90 

it is possible to evaluate that 

- the position of  Xindu is "earlier" and closer to Munich than Chengdu, more exactly

    :710 - :690 = 20 km earlier

    r7700 - r7690 = 10 km closer

- the distance between both locations, the hipotenuse, will be between 20 and 20+10 km. 

 - for advanced users:

the egocentrical direction Chengdu  / Xindu  (to earlier/to inside) is QuoVides(R) 1, see
