[OSGeo-Discuss] square vs. polar grids

[Munich Orientation Convention]

The abundance of ideas for location codes proves the demand for simple
answers to the simple question "where?", see www.volksnav.de/YouAreHere.
Street names, lat/lon and post codes aren't simple. 

 

The cities Mannheim, Brasilia etc. begun to answer the question without
street names but they adopted SQUARE grids, a self-strangulation.

Other codes also base on square grids and have only one global reference.
What costs little.

 

Polar grids have an global/urban/indoor reference, have no limitations,
support the natural angle orientation and in my case divide the horizon into
12 instead of 360 main directions and - like the OpenStandard "r100" - are
METRICAL.
