[Talk-ca] Addressing in Canvec.osm
Hi Tyler, What distance did you use? I was to use 0.0001 degree (about 10 meters in Halifax) for addressing in Canvec.osm. What would you suggest? For all, concerning adderssing tags, I am going to use... interpolation line - addr:interpolation First/Last node of interpolation line - addr:housenumber - addr:street - addr:city This is what is described as required from the wiki, except for addr:city that is optional. I can remove it from the schema but I can't replace it with anything else because this is all I can get from Canvec (and obviously GeoBase) content. Proposal?

As oh... the direction of the way is from lower # to higher house number? so it would be 3 separate passes through the data to get the 1 - road name 2 - left side (2 house numbers) - adjust .0001 degress 3 - right side (2 house numbers) - adjust -.0001 degrees If thats automatic.. that'll be awesome! ... I also cc'd feralbob for comments :) Cheers, Sam This is what is described as required from the wiki, except for addr:city that is optional.

What would you suggest? Please please *please* use metres. Merkaartor has some code that generates address interpolation ways using degrees, and it results in the distance from streets depending on the street's orientation, and looks plain ugly in any projection apart from latlon. As for the distance itself, I'd prefer 14-17 metres for highway=tertiary and below, and 20-23 metres for highway=secondary and above, if such a distinction is possible. This is based on observations from Toronto and area; I don't know about other cities. -- Victor Bielawski ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca

2 12 Interpolation Way:O---O Street:O=O This way at intersections all the numbers don't jumble on top of each other. Hi Tyle, The work you are doing is excellent, I just wanted to alert you to an issue with rural numbering (in case you are unaware of it). Our 'street' (subdivision) does not have linear numbering; that is the number sequence increases from the start of the road, but has gaps ie. 1,5,7,13,19,21. It seems to be in 100m's from start of road, with odds on the right and evens on the left. I believe that it is done this way to help emergency services find the correct residence in an emergency. There is a document from the local MD which has explanation/example plans (which I have a copy of if you want it, 745kByte) or I can send you a lat/long to check out.

Hi Simon, Thanks for bringing that up to me! I hadn't considered that as I haven't run into it yet in the urban areas I'm dealing with. There is a document from the local MD which has explanation/example plans (which I have a copy of if you want it, 745kByte) or I can send you a lat/long to check out. Sure, please send that information along to me and I can keep it in mind when I get into the rural areas of Manitoba. I haven't looked at how the StatCan data works in rural areas; they may only have address information on the specific part of the road where its necessary, but I'm not sure. The complication I can see myself running into with irregular numbering is matching where the numbered portion starts and ends in the OSM data compared to the NRN data. In the city the numbering starts at an intersection and goes to the next intersection so its easy to fit the NRN interpolation ways into the OSM data, even if they're not the same size/shape as the OSM data If there is a segment of addressed data in the middle of a rural road it might be fun to try and figure out where that maps to in the OSM data. I'll have to look at the NRN data more closely to see if I can find an instance of this in Manitoba. Thanks!

Re: [Talk-ca] Addressing in Canvec.osm
Not all street numbers are used even in the suburbs. For example in Ottawa houses with 50 foot lots have their numbers incremented in fours not two. I don't think it matters too much the interpolation will give you an approximate location which can be corrcted by some one on the ground if there seems to be a major problem.
