Re: [Talk-transit] Naptan import
Plusbus zones are polygons which are unrelated to the road network - so for Rye it covers a large polygon defined by straight lines linking each pair of adjacent nodes on the source list of defining points. The representation of this "along the roads" is inappropriate - and certainly not how it should be should be shown in terms of the zone definition intended. The Rye example is a particularly extreme example, as there are few roads in the area with bus routes - and lots of marshland and open countryside covered by the Plusbus zone.

The incorrect geometries are converted directly from the NPTG data. Some of the polygons there have duplicate nodes. Removing the duplicate nodes was a sensible choice, I think.

That looks much better :-) I noticed that the bus stops are all tagged with highway=bus_stop. Is this intentional? I thought this should depend on what people wished for their local area.

Since the source tag applies to the whole changeset it makes sense to tag only the changeset. However, I believe editors do not display changeset tags at the moment. This means changeset tags are basically not visible when you edit data. While it can be handy to see the source of an element when you edit it (e.g. I'm much less relucant to move NPE-sourced data if it does not fit with my tracks than surveyed data) this should not be a problem with the naptan-import. The naptan:-tags are a very obvious hint where the data is coming from.

[Talk-transit] NaPTAN Import
I think all outstanding coding issues have now been dealt with. There's one minor tagging issue to address - should the source tag be on the data or changesets. Otherwise, a test upload of the Surrey data is visible here - http://api06.dev.openstreetmap.org/browse/changeset/394 Comments welcomed. We're then ready to begin uploading to the main database. I will fetch a fresh copy of the NaPTAN data now, as agreed earlier last month. -- Regards, Thomas Wood (Edgemaster) ___ Talk-transit mailing list Talk-transit@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-transit
