Munich Orientation Convention in Zhangjiagang     

                                                                中文                                  other cities

Zhangjiagang 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, postal codes, house numbers etc. have logical addresses like

       Free Trade Zone   StatusQuo© ZJG   m11 r150

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

(c)2007 Munich Orientation Convention 

An outstandig point, e. g. an important bridge, a fountain, a monument etc., 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 :     m3:50  

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

This is a line situated in a distance of 50 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 StatusQuo© (where you are) for targets, buildings, crossings etc. come into existence, e. g. as shown on the picture: 

        crossing StatusQuo© ZJG    m10:20 r80    

The prefix ZJG says that the position code is valid for Zhangjiagang. 

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  

Please be aware about the fact that for the first time such codes make it possible to imagine where targets are situated even if they aren't visible on map  e. g  m6 r200 !


Secondary clock

If desired, important areas within Zhangjiagang can build an own urban clock: 

Zhangjiagang Free Trade Zone ZFTZ


According to this concept, e. g. for the crossing 

      StatusQuo© ZJG m11:15 r120    

, also an address like 

     StatusQuo© ZFTZ m4:24 r58 

can be defined, see on picture at bottom side.



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:                      Free Trade Zone FTZ   m11 r150      

If you've lost orientation on named crossing              m10:20 r80, 

so you must go

- outwards (radius r160 is more than actual r80 )


- to "later" (clockwise)   ( m11 is "later"  than the actual m10 )

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 download the demo program for pocketPC with/without GPS 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 Zhangjiagang is 

           WatchRose© m1:27 40  r86 65  

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

        Nanjing WatchRose©  m1:28 40  r85 40 

it is possible to evaluate that 

- the position of  Nanjing is "later" and closer to Munich than Zhangjiagang, more exactly

    :2840 - :2740 = 100 km later

    r8665 - r8540 = 125 km closer

- the distance between both locations, the hipotenuse, will be between 125 and 125+100 km. 

- for advanced users:

the egocentrical direction  Zhangjiagang / Nanjing  (to later/to inside) is QuoVides(R) 9, see
