<div dir="ltr"><div dir="ltr">The best way to get this process started is to side step the very valid questions people are raising about cross-layer synchronization. And to ask the question: what kinds of layers do *NOT* need to be synchronized? The answer to that question for me, is public <b>authoritative</b> data sets. These are things that are controversial and NOT currently included in OSM, and things that otherwise should certainly NOT be included in OSM. Key word: <b>authority</b>.<br><br>For the purposes of determining a plot of land or an Eruv, you need the government or clergy sanctioning it. That excludes me. And, at the point that it excludes me, I say give them a layer in OSM, or allow them to self-host their own remote layer with an installer. We can all have layers. We're solving a problem there.<div><br></div><div>But does that layer need to be synchronized with the real world, as we know and experience it? No. Absolutely not. In fact, it's not a feature that it is. And the idea that an Eruv is an area designated by a fishing string on electrical poles is nonsense, and an attempt to pull the wool over the eyes. Again, you need only connect another pole into the barrier network and drape it with string. It would have equal standing geographically, but it doesn't have the _authority_ of an Eruv. IMHO, it would be vandalism to ignore the authority and mark it as such. For me, all that stuff should be purged.</div><div><br></div><div>That includes state boundaries too: 200 years ago a state may have been defined by a river. But if that river changes course and we update, the state boundary doesn't typically change. This an indicator it's an area by fiat and nothing more, and we can easily use layers to fix that. In fact, that the state can not share the boundary with an actual living river is a feature.<br><br>Taking it another step further, we side step all the questions about national naming too: kurdistan/turkey, palestine/israel, etc. Delegate it to authoritative layers which can call them whatever you want.<br><br>My ideal OSM is simple. I go outside and observe something, I can edit it. When you're not concerned with my observation or it's not enough, you need authority and layers will solve that.</div></div><br clear="all"><div><br></div>--<div dir="ltr"><div dir="ltr"><div>Evan Carroll - <a href="mailto:me@evancarroll.com" target="_blank">me@evancarroll.com</a></div><div>System Lord of the Internets</div><div>web: <a href="http://www.evancarroll.com" target="_blank">http://www.evancarroll.com</a><br></div><div><span>ph: <span title="Call with Google Voice"><a href="tel:+1-281-901-0011" target="_blank">281.901.0011</a><br><br><img src="https://stackexchange.com/users/flair/42701.png"><br></span></span></div></div></div>
