    <p>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:</p>
    <p>  o On the building as an area, traced by hand and added by hand.<br>
    </p>
    <p>  o On the centroid of the parcel as a point.</p>
    <p>  o On an address interpolation way, which hops from parcel point
      to parcel point.</p>
    <p>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.<br>

              <div>Greetings!</div>

              </div>
              <div>I've been recently thinking about importing
                addresses for San Francisco, CA.</div>
              <div>It looks like there has been interest in
                this kind of import (the page devoted to it was created
                in 2010, <a href="https://wiki.openstreetmap.org/wiki/San_Francisco_Address_Import" target="_blank">https://wiki.openstreetmap.org/wiki/San_Francisco_Address_Import</a>).</div>
              <div><br>
              </div>
              <div>So, please, consider this message as my
                "community buy-in": does anyone have any objections
                related to this possible import?<br>
              </div>
              <div>By now I've obtained a permit from the data
                owner (<a href="https://data.sfgov.org/Geographic-Locations-and-Boundaries/Addresses-Enterprise-Addressing-System/3mea-di5p" target="_blank">https://data.sfgov.org/Geographic-Locations-and-Boundaries/Addresses-Enterprise-Addressing-System/3mea-di5p</a>)
                and almost finished writing my code for matching
                buildings to address points.</div>
              <div><br>
              </div>
              <div>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.</div>
              <div><br>
              </div>
              <div>
                <div>Looking forward to receiving your
                  feedback!</div>
                <div><br>
                </div>
                <div>p.s. I have some experience in importing
                  addresses (e.g., see <a href="https://wiki.openstreetmap.org/wiki/Import/Catalogue/MassGIS_Addresses" target="_blank">https://wiki.openstreetmap.org/wiki/Import/Catalogue/MassGIS_Addresses</a>)</div>
