Re: [Talk-ca] Advice on Addressing
Individual buildings is definitely preferable to interpolation ways. For adding address coverage in Fargo, ND, I used the 'audio mapping' technique detailed on the wiki while riding my bike up one sidewalk and then down the other on each street. It goes very fast and works very well. I also gather building:levels data at the same time as well as whether the address is for a house or apartment building. So my audio recording sounds like... Number 102 is a 1 storey house, number 104 is a 2 storey apartment, etc... Hope this helps. -AndrewBuck ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
Re: [Talk-ca] Advice on Addressing
I was pretty disappointed with the results I got from (mapquest's) Nominatim when I tried to geocode Doors Open Toronto's data. I found about a third of the results were clearly wrong, and haven't eyeballed the rest on a map to see how far off they are. Toronto's got pretty good address range entry, too. Sure, I hadn't cleaned up the data in any way (so there was some random noise about unit number formatting, and I don't think there was a single instance of the One True Canadian Address format in the whole list) but the results were disheartening. So, no answer from me, but I'm interested in hearing how this goes. Cheers Stewart ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
Re: [Talk-ca] Advice on Addressing
Individual addresses are always preferable to interpolation lines, interpolation lines are just an approximation so if you have all the addresses in a block you shouldn't also have interpolation lines as the latter duplicates the former. As for how to tag the addresses, if they're buildings with only one address I prefer put the addresses on the buildings. For more complicated situations with multiple addresses per building you'll often end up with points for addresses, and these points often also have shop information.

Re: [Talk-ca] Advice on Addressing
Much has already been said. A good tool to collect housenumbers on an Android phone is keypadmapper: http://wiki.openstreetmap.org/wiki/KeypadMapper I've mostly mapped interpolation lines in my Montreal neighborhood. The problem here is that each apartment has an individual housenumber, meaning that if you have, for example, a triplex you can easily end up with 8 different numbers for just one building, making individual nodes a huge pain. One note about the linked example: If you've mapped all individual houses on a block, I'd delete the interpolation line or add the addr:inclusion tag to provide other mappers with accuracy information: http://wiki.openstreetmap.org/wiki/Addresses#Using_Address_Interpolation_for_partial_surveys Harald.
