Re: [Talk-transit] [Talk-gb-westmidlands] NaPTAN merge tool
I agree that this makes sense - the only change I would want is for the green (i.e completed) status to also require the presence of shelter=yes/no i.e presence of shelter key regardless of value 2009/4/3 Andy Robinson (blackadder-lists) ajrli...@googlemail.com Christoph, http://www.mappa-mercia.org/cgi-bin/naptanmerger.wsgi/ Looking good :-) A few comments on how this might work. Suggestions only for you to think about and to elicit comments from others. Green would show a stop that's got merged data, i.e. it's a done deal and no further work is required. To flag this as green you would check for: highway=bus_stop The presence of the naptan:atcoCode key naptan:unverified=yes tag is no longer present route_ref tag is present Orange would be one step down where one or more of the above are false except for the following specific cases: Yellow (or some other colour) would be a NaPTAN imported node which contains: no highway=bus_stop tag The presence of the naptan:atcoCode key naptan:unverified=yes tag is still present Blue (or some other colour) would be a node which has highway=bus_stop but no naptan tags indicating that its OSM suryeyed data alone. Red, to denote a naptan node that has no physical presence on the ground and no known use as a bus stop. This would be a node containing: no highway=bus_stop tag naptan tags present physically_present=no tag present Thoughts?

[Talk-transit] GPS traces in Central Birmingham
Hi Peter The relative absence is mainly down to experience that the traces were so unreliable as to be only a guide and a lot of streets are estimations only. I tried using a compass to get bearings but standing in the middle of a road with a compass causes a lot of disturbance so I desisted. Perhaps being on the top deck of a double decker reduces the bouncing effect of the GPS signal from the surrounding buildings.

Re: [Talk-transit] NaPTAN import
2009/4/3 Brian Prangle bpran...@googlemail.com: Hi Thomas From our west mids meeting last night a number of requests and queries came up 1.Can you import Wolverhampton - the guys up there are ready to have a crack Ok, done. 2. Coventry will not be far behind but hold off until we've checked with the major contributors there 3. We'd like to see the NaPTAN fields LocalityName and Bearing imported This is an NPTG field, none of the NPTG stuff has been looked at yet. 4. We're not sure if stoptypes CUS, TXR STR BCQ and BCS have been imported CUS are in, but not tagged in data, there's no TXR or STR in the West Mids dataset, BCQ, BCS are in, but not tagged as such since they're essentially the same as BCT for our purposes. 5. We're not sure if your local_ref field is working correctly -essentially it's just repeating the naptan:Indicator field It's a filtered version of the Indicator field, where a reference can be pulled from it intelligibly. I'll be writing a short set of guidelines and also a summary of what we've found for the import wiki page - to be published shortly As a group we've decided to rely on our gps surveys of where bus stops are and move the NaPTAN data to that location for merger with our data. The feeling is that earlier bus stop surveys need to be repeated much more precisely - examining some of our earlier data suggest we weren't as accurate as we needed to be. Christophe seems to be making good progress with the visual verify/merge tool. Peter - we're very keen to get our hands on aerial imagery - what needs to happen to get this under way?
