hi,<br>
i walk a lot, and would like a routing engine which understands i can<br>
take a direct route across an open public space, such as a park,<br>
without needing a footpath to be explicitly drawn in. the existing<br>
routing engines don't seem to understand this.<br>
<br>
or am i missing a tag? do i need to tag parks, etc. with "area=yes"<br>
"foot=yes", "access=yes" or would that be a case of "tagging for the<br>
routing engine"<br>
<br></blockquote><div><br></div></div></div>Firstly note that routing across areas is (theoretically) much harder than routing along ways (Non-polynomial time VS polynomial time).<br><br>Secondly note that the problem is not restricted to pedestrian routing, e.g. parking areas. There have been cases where people mapped the road surface as areas, although they would then also have ways running down the centerline.<br>
<br>Supporting areas is on my list of things that I would like to do, but there are many other things in front of it. I recently added dragable routes to the Osm.org Routing Demo. I improved the endpoints. Negotiated for a better server. Routing instructions and translations. And for Christmas I want a mobile application for large scale collection of house numbers.<br>
<br><br></blockquote></div></div><div>I definitely second your call for a mobile app to easily collect house numbers. A single-purpose app could be very simple. Would you want to have something graphical (user pinpoints address on map on-screen) or something even simpler (user enters housenumber, selects street based on location or accepts best match, address node is sent to OSM). In the latter case, which is what I would prefer, how would you deal with GPS inaccuracy?<br>
<br></div></div></blockquote><div><br>Non-graphical. The streetname is not added to the address PoI. Nominatim is smart enough to take the closest street.<br><br>If I travel down a street it, I want to be able to tell it that house 23 is on my left using just 3 or 4 keystrokes / taps.<br>
