<br> <span style="font-family:sans-serif">I've made some good progress, and I think it's at the point now where it's ready for others to look at. I've made a draft proposal on my user wiki page here:</span>

<br>
<br> <span style="font-family:sans-serif">I thought I'd share this before moving it to a subpage of New York, and adding it to the catalogue wiki page, as I'm not sure it has all the information that is expected of these pages.</span>
<br>
<br> <span style="font-family:sans-serif">In particular, one thing I could use some more clarity on is: what do people usually use to split up and track work for imports? I saw the HOT Tasking Manager, but it seems like not just anyone can make projects on this tool. Am I supposed to just ask someone to make a project for me, or give me permission to make one myself, or is there another tool people use?</span>
<br>
<br> <span style="font-family:sans-serif">A sample of the data from this converter program can be downloaded here:</span>
<br>
<br> <span style="font-family:sans-serif"><a href="https://skyler-public.s3.amazonaws.com/osm/nys_gis_address_points_import_sample_east_north_greenbush.zip" target="_blank">https://skyler-public.s3.amazonaws.com/osm/nys_gis_address_points_import_sample_east_north_greenbush.zip</a></span> <br></div></blockquote><div><br></div><div>I still have some questions about conflation, because there are some odd cases that are pretty common in that data set.</div><div><br></div><div>There's some delay in actually propagating updates into the distributed E911 address points. For instance, the addresses along <a href="https://www.openstreetmap.org/way/813453708">https://www.openstreetmap.org/way/813453708</a> were surely not in the database when I mapped them. The subdivision isn't finished yet, and I have no aerials showing it. I put on my "urban camouflage" (orange vest, hard hat, work boots, clipboard) and walked through. It was sort-of open to the public. The roads were done and there were a couple of model houses built. You could stop in and get shown around. I was followed for a while by a late-model Lincoln driven by a lady who had 'realtor' written all over her. Eventually she got bored. Every building lot was marked with a stake with the house number, and I snagged coordinates from those. How likely am I to have caused trouble down the road with failed conflations?</div><div><br></div><div>Apartment and condominium complexes are mapped inconsistently. For instance, the building numbers for <a href="https://www.openstreetmap.org/way/491144551">https://www.openstreetmap.org/way/491144551</a> are just strung out at more-or-less equally-spaced intervals on the entrance road. The housenumbers were visible on the buildings, and I mapped them on the buildings. Likely to cause trouble? (Also, there's a spurious "1515 Hillside Avenue" on the junction of the entrance road.</div><div><br></div><div>The next subdivision over, <a href="https://www.openstreetmap.org/way/491144554">https://www.openstreetmap.org/way/491144554</a>, has the county showing neat clusters of address points - that are not even close to being aligned with the buildings. The building numbers stop with 608. Christian Court is not shown, and there's a spurious "1503 Hillside Avenue" on the entrance road.</div><div><br></div><div>The next one over, <a href="https://www.openstreetmap.org/way/553341585">https://www.openstreetmap.org/way/553341585</a> has a spurious '1453 Hillside Avenue' in the middle of the complex. I know that the buildings have addresses on Alice Wagner Way, that are not shown. I didn't trouble to record them when I walked the neighbourhood, because ordinarily I can recover housenumbers from the county. Not this time! One of these months I'll make it back in there and grab them. </div><div><br></div><div>There are also some fantasies in the data. In the vicinity of <a href="https://www.openstreetmap.org/way/553341585">https://www.openstreetmap.org/way/553341585</a> there is a chain of points strung out along an entirely fictitious 'Greylock Avenue' (which I presume belongs to a subdivision for which planning permission was refused. Some of the nodes are in land that now belongs to the township.) The varous government GIS departments have goofed here as well. There are two buildings with Becker Drive addresses and one with an Alandale Avenue address that are misidentified as being on this fictitious street. (Caveat - I actually need to get in there and recheck. I'm quite certain that the street does not exist, but less certain that there are no buildings with addresses on it.) </div><div><br></div></div><div>None of these things are showstoppers; it's mostly better than what we have. But it's good to look at the edge cases and make sure that we at least do something reasonable - and in particular, to make sure that we don't spoil work that mappers have already done.</div><div><br></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature">73 de ke9tv/2, Kevin</div></div>
