[OSM-newbies] Adjacent areas

[Werner Horsch]

To Pieren:
You are completely right until you have to draw the inner of a boulevard
which is 20 blocks long. 1 relation against 20 new blocks
Now imagine when some one moves one of the streets, you have to redraw the
inner XX as well. It's a trade off, just try it and take your choice


To Richard Weait:
This is the limitation of our drawings, our ways have no thickness and I'm
gtratefull that for, that's what makes our drawing job easier.
On the other hand we don't have the precision to draw that, using satelital
images and GPS units your prison can have nice errors in size and location
rounding the 20mts or even worse if your image needs offsets
I don't think someone who use the map will complaint about this, just give a
try and see how it looks like
