The data contains two pieces of information on plusbus zones: The nptg database has a list of all plusbus zones with their extent given as a list of locations which form a polygon covering the hole zone. In the naptan data the busstops can have a list of PlusbusZoneRef tags which list the plusbus zones a particular busstop is part of. > To be clear I don't think anyone is suggesting we should never > import Plusbus zones, it is just a matter of if it is in the first > pass and at the end of the day that is going to be up to the person > writing the code! The plusbus zones in nptg can be imported as ways. Each of these ways and all busstops in the zone can then be put into a relation. While the importing of the plusbus zone polygons should not be very tricky. I do not know easy it is to build a relation in the importer. However, I should be quite easy to update the busstops at a later stage and add the plus bus zones.
