When two schools share a building, it's common for the dividing line to shift from year to year depending on the makeup of the student body. Mapping this as two school nodes in a building is probably the best way of doing this, as the *entrances* to the schools are usually separate, and don't change over time. -- Mark _______________________________________________ talk mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk
