I sent this mail because almost all of the data I've seen available for import in the US (all the way from individual municipalities to TIGER's shapefiles) has this left/right-from/to scheme for addressing information. If the expectation is that we will always be following the Karlsruhe schema (with separate ways on each side of the road centerline), then importing this addressing data will be next to impossible*. -Ian * Ok, not "impossible", but the import size would triple and the CPU time to compute the new addressing-only ways might make it hard for the "regular mapper" to do.
