[OSM-talk] 'Distance to feature' maps?

[Gary68]

another thought: it would also be possible to create additional nodes
(where i.e. type=dist, dist=xyz) in xml format that could be fed into an
existing osm file. the resulting file could be rendered by KOSMOS. all
this would need is an additional rule for the new distance nodes.

then you would have nicer maps :-))
