Steve, I don't see how this would improve performance. Maybe I am using the wrong parms and don't hit the code, but in my profiling data I only see the IdentityHashMap in addRoadWithoutLoops() and the rules.resolveType(..) calls. Do you have a case where this addtag/gettag technique might slow down the program? Gerd

Hi
hmm, do you think about storing the information in e.g. a bitmask rather than in tags?
Yes, if I had done that part, I would have tried to go directly from osm tags to properties on the Element, rather than the two stage process of osm tag to mkgmap:* tag.
