Munich Orientation Convention in   Xi'an    

                                                                                                          中文                     other cities

Xi'an 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

              University of Science and Technology      StatusQuo© XIAN  m5 r30

              Terra Cotta army                                                                   m9:15 r60

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

An outstanding point, e. g. the Bell tower, 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      m3:5           ( read   "emm three point five"   or   "emm three five" ). 

This is a line situated in a distance of 5 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   m1:8 r22

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 above mentioned targets aren't on map but 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:                   University of Science and Technology  m5 r30       

If you've lost orientation on named crossing                                  m1:8 r22

so you must go

- outwards (radius r30 is more than actual r22 )


- to "later" (clockwise)   ( m5 is "later"  than the actual m1 )

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 Xi'an  is 

          WatchRose© m2:105  r77 35     

What is this good for? Just comparing the codes for example of Xi'an and  

          Xianyang WatchRose©  m2:120  r77 10 

it is possible to evaluate that 

- the position of  Xianyang is "later" and closer to Munich than Xi'an, more exactly

    :120 - :105 = 15 km later

    r7735 - r7710 = 25 km closer

- the distance between both locations, the hipotenuse, will be between 25 and 25+15 km. 

- for advanced users:

the egocentrical direction Xi'an  / Xianyang  (to later/to inside) is QuoVides(R) 10, see
