<div dir="ltr"><div>Hi Abhishek</div><div><br></div><div>1. I think it's good to have a guide. But I'm familiar with discussions through the standard OSM ways (Wiki pages, Diaries). I find GitHub not easily accessible. Also, the danger exists that discussions are finished on GitHub leading to changes in the guide, however omitting changes on the Wiki pages. I think I would prefer to have a single point of discussion in the standard OSM way. A possibility is this page: <a href="http://wiki.openstreetmap.org/w/index.php?title=Talk:Lane_assist&action=edit&redlink=1">http://wiki.openstreetmap.org/w/index.php?title=Talk:Lane_assist&action=edit&redlink=1</a></div><div><br></div><div>2. Shortly after Imagic launched the lanes suffix I helped improving some issues. However, I always missed professional input since I think inventing a good mapping scheme for supporting a lane assist is extremely complex. Telenav had a bit of a discussion two years ago, that was it. I think it's good to have Mapbox involved, but where are companies like TeleNav, GeneralMagic and NavMii in this discussion?</div><div><br></div><div>3. One of the difficult topics is a situation involving two junctions. Though I like the KISS way of the :lane suffix (avoiding a relation), in case of two junctions a relation might be unavoidable, like in this situation: <a href="http://map.project-osrm.org/?z=18¢er=51.896213%2C4.540266&loc=51.896370%2C4.539505&loc=51.896218%2C4.541039&hl=en&ly=&alt=&df=&srv=">http://map.project-osrm.org/?z=18¢er=51.896213%2C4.540266&loc=51.896370%2C4.539505&loc=51.896218%2C4.541039&hl=en&ly=&alt=&df=&srv=</a></div><div>Yep, the lane assist should help the driver by showing the left lane at the starting point. Don't know how to tag it</div><div><br></div><div>4. The lack of involvement of companies building navigational apps might not help getting OSM apps to the standard of apps like TomTom. In this situation: <a href="http://map.project-osrm.org/?z=16¢er=51.944695%2C4.532418&loc=51.934661%2C4.536710&loc=51.946632%2C4.508986&hl=en&ly=&alt=&df=&srv=">http://map.project-osrm.org/?z=16¢er=51.944695%2C4.532418&loc=51.934661%2C4.536710&loc=51.946632%2C4.508986&hl=en&ly=&alt=&df=&srv=</a> MagicEarth does not show any lane assistance. It probably thinks this huge intersection is a normal highway with a normal motorway exit, which should not be showing up. I don't know if its a programming error or a case where we need an extra tag like: lane_assist=yes, thus helping the router to always display the lane assist.</div><div><br></div><div>5. A further topic might be the definition of the lanes tag, see this diary entry: <a href="http://www.openstreetmap.org/user/imagic/diary/28309">http://www.openstreetmap.org/user/imagic/diary/28309</a></div><div><br></div><div>Cherio, Johan</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2016-03-10 11:03 GMT+01:00 Abhishek Saikia <span dir="ltr"><<a href="mailto:saikia.abhiitc@gmail.com" target="_blank">saikia.abhiitc@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div style="font-size:12.8px">Hello everyone,</div><div style="font-size:12.8px"><br></div><span style="font-size:12.8px">As a part of a recent push to improve OpenStreetMap navigation data, our team at Mapbox started collaborating documentation to create a comprehensive wiki on "</span><b style="font-size:12.8px"><a href="http://www.openstreetmap.org/user/saikabhi/diary/38106" target="_blank"> Guides to improve navigation data in OpenStreetMap</a></b><span style="font-size:12.8px">". This mapping guide is still not complete and the team intends to keep on adding new features to the guide and make it more comprehensive so that it can be a reference to anyone who wants to contribute navigation data on OpenStreetMap. It will be helpful and great if the community can go through the guide and give their valuable feedback.</span><br><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">Regards,</span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">Abhishek</span></div></div>
