[OSM-newbies] How to draw land-use areas

[Charlotte Wolter]

Michel,

         Thanks! That seems very sensible.
         What he did, most often, was to put the margins of land use 
down the middle of the street. But, the street is not, for example, a 
residential area.
         Also, because he had the margins of land use intersect with 
the street, you would have to recreate the street if the land-use 
margins changed.
