Re: [OSM-talk] addr:interpolation and data consumers
It's not always that easy. "3D housenumbering" has no clear tagging rules and sometimes it's hard or illegal to get close enough to see which number is used for which building/entrance. In other situations the mailboxes are not located where the houses are and the houses have no addresses on them, making it hard to know which mailbox belongs to which building. Interpolating when you know start and finish is more honest than guessing. /Andreas Skickat från min iPhone > 20 nov. 2016 kl. 17:47 skrev nebulon42: > > Hi, > > I have written an address QA script for Austrian addresses.

Yes, for mappers the speedup can be tremendous, in some cities you just have to walk down one street and for every side street you'll immediately see, on the street sign, that this block has house numbers 1200 to 1299 or so. Sometimes the numbering is so regular that this enables you to map house numbers for the next couple blocks down the side street. Consumers will often try to simply dissolve the interpolation line into points which of course has its downsides in schemes like this where 100 interpolated house numbers are assigned but only 10 houses might exist. (I wonder if we need an interpolation type of "sporadic" for that ;) Surprisingly, I have occasionally been asked by paying customers to produce shape files where each street segment has the attributes "house number left from", "house number left to", "house number right from", "house number right to" - which is of course less precision than usually offered by OSM's individual house numbering, but this seems to be a format commonly used by providers of proprietary data and hence there's software that expects that format.

That is the right thing to do. > What is the opinion on addr:interpolation here? I cannot speak for other areas, but twenty years ago every town in my county renumbered their roads so that your house number is 1/200th of the mile down your road. When a new house gets built, there is no question what its house number is. Now, for my area, I've numbered all the houses (well, mailboxes, because that's where the number is) AND used those points to create address interpolation ways AND the property centroid has a node with the cadastral address on it, as well. Mostly I did that on bicycle rides near my house; not everywhere. And mostly that was done to test the accuracy of mailbox vs cadastral centroid vs interpolation. And y'know? It's all good. Any one of them works. -- --my blog is athttp://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

I know that addr:interpolation is an established tag, but the Wiki also says: Addr:interpolation is a convenient method for mappers to add many addresses at once. Without an addr:inclusion tag, it implies a complete collection of addresses along the line. The calculated addresses may not fall in the center of each building, but they are certainly useful to OSM. ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Interpolation was only intended as a way to get going quickly and easily with lots of addresses. And it has another use: Some non-OSM data sources use a format where a "street" has attributes giving the house number range on the left and right side. This can be reasonable easily be transformed into the addr:interpolation format for importing that data into OSM. It is here like with everything in OSM: There is a trend towards more detail. If you have more detailed information, great. If not, it is better than nothing.

[OSM-talk] addr:interpolation and data consumers
Hi, I have written an address QA script for Austrian addresses. Now I'm asked to support addr:interpolation. While the script is specific to Austria the more general problem of addr:interpolation is not. In my opinion addr:interpolation is of little value for data consumers. Personally, I prefer addresses on nodes or buildings where the location of the address is clear. addr:interpolation rather leaves this open. I know that addr:interpolation is an established tag, but the Wiki also says: "As long as we don't have a node or building outline for each house(number) along a way, it's also possible to use automatic number interpolation." (https://wiki.openstreetmap.org/wiki/Addresses#Using_interpolation) For me that sounds like: use it until there is something better/more accurate. I tend to replace addr:interpolation with addresses on nodes or buildings when I see them and more accurate data is available. What is the opinion on addr:interpolation here?
