'Peak district national park' for example needs a boundary, but there is one hell of a lot of detail contained within ;) And as you say there is no need to break large areas of landuse='farm' if there are many footpaths and roads crossing it - BUT at some point it may be necessary to be able to calculate the 'cultivatable area' and this needs the detail to remove those areas of roads and the like. I think this is where the a/b camp do not actually conflict, as long as the dimensions of the roadways can be calculated from something. But at some point it WILL be necessary to actually draw the 'cultivatable area' and then the extra elements make life a lot easier than trying to extract width and side area information from tags on the single roadway.

If the data is available to 'micromap' then this should be the norm and I have no doubt at some point even roads will be represented by areas, BUT with a macro view that presents things as a simple 'way based' view. > Of course, nothing is ever final ... With ever more people adding data, the 'macro' view is straining to contain the micro details, so this IS going to carry on evolving. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
