OSM documentation thus far has allowed addresses in either nodes or areas. I've been personally assigning addresses on parcels to the building area, and for apartments with more than one address per parcel, using nodes. But that's because I'm used to the Google Mapmaker methods from yesteryear.<br class=""><br class=""><br class=""><br class=""><br class=""><br class=""><br class="">-------- Original Message --------<br class="">On Jul 14, 2018, 12:26, Andy Anderson < aanderson@amherst.edu> wrote:<blockquote class="protonmail_quote"><br class=""><div class="">The 911 address database has locations (or tries to have locations) right down to the entry door. So if you have a two-unit building with two addresses and one entrance in front and one entrance in back, those entrances will have separate data points at the entrances. The reason, of course, is so that first responders don’t waste time trying to locate the correct entrance. Importing this database and setting up a programmatic routine for updating it regularly would seem to be the best practice.<br class=""><div class=""><br class=""></div><div class="">— Andy</div><div class=""><br class=""><blockquote type="cite" class=""><div class="">On Jul 14, 2018, at 11:51 AM, Angela Morley <<a href="mailto:amorley@protonmail.com" class="">amorley@protonmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">My thoughts on this are that this is something we need to do to make OSM truly useful.
