This is a direct analogy to how I see unnamed landuse for developed land. There is an application for landuse, and for density. However, I don't understand why these are better left to users rather than automatically generated. If we want to support landuse for developed land moving forward, I highly suggest automatically inferring it from the contents of polygons created in the method outlined in my reply to Joseph Eisenberg. =)</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Oct 11, 2022 at 1:34 PM Evan Carroll <<a href="mailto:me@evancarroll.com">me@evancarroll.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Lyft has been adding thousands of Polygons around Houston for Retail and Residential and Industrial Areas. I'm just wondering what the motivation here is for Lyft's behavior, especially in Texas. It seems like a lot of bloat on OSM. IMHO, these polygons don't add any value: they're not describing what things are, and they're frequently incorrect. Houston doesn't have zoning: stating what something is today as if it was a zone is problematic anywhere (as at best it's only ever administrative where there is zoning) but even more so in Houston where with enough money you can buy the property and put an industrial plant there (assuming the property has no bylaws). Sure that's just routine maintenance but what is the value with that maintenance?<div><br></div><div>If we know what every individual building is (which is the ideal), what information is conveyed by telling me that 80% or some unquantified inexplicit percentage of buildings in a grouping are of type Industrial?<br><div><br></div><div>And a lot of these polygons cover _only_ one property. Which it seems isn't permitted by the wiki, but that also doesn't add any utility over the building itself.</div><div><br></div><div>Some examples of these nameless sections are,</div><div><br></div><div>* w1101484647 by A_Prokopova_lyft</div><div><br>Across the street from that one is three identical polygons by Emey_lyft in the same place</div><div><br></div><div>* w1101205150</div><div>* w1101204670</div><div>* w1101392713</div><div><br></div><div>In case you think that's unique, right below it Emey_lyft did it again with three identical polygons.</div><div><br></div><div>* w1101205149</div><div>* w1101204669</div><div>* w1101392712</div><div><br></div><div>I'm assuming the triplicating is an innocent mistake, and not an attempt to inflate a quota. But, I just want to understand what is the use case for highlighting *everything on the border of every major highway and primary road* with "Retail Area" even without triplicating.</div><div><br></div><div>Moreover, with polygons like w1096234140, how is that useful when you lump in one motel and three buildings which OSM has *no information about* as a "Commercial Area"? Likewise, how is w1096234140 a "Retail Area" it covers 12 buildings and we only know one is a Post Office, the other is a Dunken Donuts, and "Houston Skate and Dance" exists somewhere inside it?</div><div><br></div><div>None of this is relevant to any areas WITH names: I'm all for these. IE, "Braeswood Squre", or "Meyer Park". Those "Areas" have a name which is useful to the community and the sign is visible for the retail campus, but seems most of Lyft's contributions are nameless (all of the ones I've seen) .They seem to be outsourcing what could otherwise be done more correctly with better data, automatically: if we know what each business is inside the polygon, we can create effective "Areas" using spatial clustering.</div><div><br>Should we better define when these areas should be used and not used? Can Lyft tell us what the business case is for funding these contributions to OSM? How are they used to create value to our users?<br><br>(This is not a call out, and I want no part of any corrective action on the two people mentioned. I'm only looking to provide concrete examples so we can better draft policy.)</div><div><div><br><div>-- <br><div dir="ltr"><div dir="ltr"><div>In the event this email pertains to Real Estate, <a href="https://texreg.sos.state.tx.us/public/readtac$ext.TacPage?sl=R&app=9&p_dir=&p_rloc=&p_tloc=&p_ploc=&pg=1&p_tac=&ti=22&pt=23&ch=531&rl=20" target="_blank">Texas law</a> requires all license holders provide to prospective clients the following forms: <a href="http://docs.evancarroll.com/realestate/iabs.pdf" target="_blank">Information About Brokerage Services</a>, <a href="https://www.trec.texas.gov/sites/default/files/pdf-forms/CN%201-2.pdf" target="_blank">Consumer Protection Notice</a>.
