Hi all! With the excellent resolution of the nearmap images, the smallest detailscan easily be added. But is this always a good idea? Have a look at http://www.openstreetmap.org/?lat=-32.073593&lon=115.755062&zoom=18 The footways along Duoro Road and Harbour Street (but not the one between them!) do not carry any information IMHO, but clutter the map display, especially on GPS units. With three times as much nodes per meter of the street(the actual road + 2 footways), data processing and editing is getting ever more resource hungry.
For pedestrian routing, the same information can be represented by adding pavement=left/right/both (I think there was a proposed tag, but I can't find it on the map features page) to the highway and highway=crossing at the crossing nodes (where currently there are mapping errors, because the footways and highways are not connected). What is lost, is precision of the map display at the meter-scale, i.e. at the scale of GPS accuracy. I don't think there is any tag that currently renders. One might imagine having a wider border of the road on the side of the pavement, in the correct color (footway/cycleway/path). This even has the advantage that the pavement remains visible on smaller zoom levels, where in 1:1 mapping, the overwide drawing of the roads usually hides it. IIRC there was a proposed implementation for osmarender doing sth. along these lines a while ago. What is everybody's opinion on this? Map whatever you can, or abstract certain features?
