Hi all, see this thread : http://gis.19327.n5.nabble.com/Commit-r3632-fix-possible-message-internal-er... I think Anor Carlos pointed out that mkgmap should not ignore a more or less valid addr:interpolation way. This can happen when someone adds a POI with addr:housenumber and addr:street and doesn't connect the POI node to the addr:interpolation way. Or when someone adds the way without recognizing that the POI has a valid address. Up to now mkgmap prefers to ignore the complete addr:interpolation way when such a node is too far from the interpolated position and "too far" means 5 m, which is probably too restrictive. I guess this is likely to happen and I've changed the code to add a message to the log with r3634. Attached is a patch that changes the tolerated distance to 40 m and further improves logging. If I hear no complains I'll commit this patch on monday. @Anor: Please try the binary at http://files.mkgmap.org.uk/download/279/mkgmap.jar with enabled logging, e.g. uk.me.parabola.mkgmap.osmstyle.housenumber.level=INFO Gerd
