[Russell Nelson]

It was an experiment, to see how accurate the three methods could be. 
That road, and many around it, are not completely built-out. When a new 
building is built on an empty parcel, it will have an address 
immediately.  When a new address is assigned to a new (split out) 
parcel, the interpolation will give it an address immediately.

Oh, wow!
Maybe that's fine, but to me it looks like duplicated info. As far as I
understand, extrapolation lines are needed in areas where buildings are not
mapped yet and, hence, the extrapolation/approximate location of the
address is the best one can get. If the address is precisely assigned to a
building, why would one need the same address on the extrapolation line?
But, again, that's just my opinion and maybe I'm overlooking something
important.

Re: [Talk-us] Import of addresses for San Francisco, CA

[Russell Nelson]

I have done this in the area around Potsdam, NY. Assigning the address 
to the centroid of all the points that describe the parcel works quite 
well. It's not perfect, though. Look at May Road. I've entered addresses 
there in three different ways:


  o On the building as an area, traced by hand and added by hand.

  o On the centroid of the parcel as a point.

  o On an address interpolation way, which hops from parcel point to 
parcel point.


The addresses are, as a rule, close enough to the houses to be well 
worth the effort it took to import them. But, go look at it yourself.

I've been recently thinking about importing addresses for San 
Francisco, CA.
It looks like there has been interest in this kind of import (the 
page devoted to it was created in 2010, 
https://wiki.openstreetmap.org/wiki/San_Francisco_Address_Import).


So, please, consider this message as my "community buy-in": does 
anyone have any objections related to this possible import?
By now I've obtained a permit from the data owner 
(https://data.sfgov.org/Geographic-Locations-and-Boundaries/Addresses-Enterprise-Addressing-System/3mea-di5p) 
and almost finished writing my code for matching buildings to address 
points.


If there are no objections, I'll go on with organising all 
documentation and sharing the code/resulting .osm-files for review by 
OSM community.


Looking forward to receiving your feedback!

p.s. I have some experience in importing addresses (e.g., see

Re: [Talk-us] Import of addresses for San Francisco, CA

[Michal Migurski]

One building can definitely have more than a single address.

Addresses provide postal delivery information and don't necessarily correspond 
1:1 with other concepts like physical buildings or legal parcels.

Re: [Talk-us] Import of addresses for San Francisco, CA

[Joseph Eisenberg]

Legally in San Francisco does the address refer to the property, the
building, or the entrance?

While I'm from California originally, I admit that I don't know the
definition of an address there.

If one building can have more than one address (based on separate
entrances), then it would be best to use nodes.

I support this import.

I would also support the import of addresses for neighboring Oakland, CA.
