Hi WanMil,

Ahh, that's fine. Unfortunately it shows the big problem of mps: thery are much too complicated (but this is not relevant for mkgmap - we have to support it until they are replaced by another OSM data structure).
Does that also mean that we should another check for that?
yes, I did not yet look deeply into the code, but I guess we can use this rule to simplify the routine that joins ways? Question is: what should happen if a relation doesn't meet the criteria? Ignore it completely or ignore elements that are invalid?

Hi Gerd, I don't think that the routine that joins ways will become easier. The task is still the same (join n ways at point p) and the existing routine does not have any error handling (like a backtracking algorithm when a join does not lead to a closed polygon). So an additional warning should be enough from my point of view. WanMil
