<div dir="ltr">Seeing this dataset contains all kinds of bike lanes, from sharrows (cycleway=shared_lane) to cycle tracks, make sure you don't mix them up. Maybe it would even make sense to conflate them separately, i.e. 1) conflate sharrows, 2)
conflate
bike lanes, 3)
conflate
cycle tracks 4)
conflate
pathways. I'm saying "conflate" because 99% of those features are probably already on the map, so for the most part, you'll be just detailing the tags. By no means you should delete any existing ways. <div><br><div><div>I see each segment has TYPE_VOIE tag, so first of all, you should figure out which value corresponds to what. For example, TYPE_VOIE=1 looks like for sharrows (cycleway=shared_lane), TYPE_VOIE=3 for painted bike lanes (cycleway=lane), etc. Perhaps the city website has its own map that has a legend to help you figure it out or you may need to check that on the ground.</div><div>Once you have that sorted out, look at other tags, such as,</div><div>- SAISONS4 - could be useful for pathways to indicate whether they are winter-maintained. See winter_service OSM tag: <a href="https://wiki.openstreetmap.org/wiki/Key:winter_service" target="_blank">https://wiki.openstreetmap.org/wiki/Key:winter_service</a></div><div>- TYPE_VOIE2 - not sure, maybe encodes something like width, surface, etc - could be useful in setting those tags. Need to investigate.</div><div>- NBR_VOIE - number of lanes? For painted bike lanes NBR_VOIE=1 probably means there is a bike lane only on one side of the road</div><div>- Ville_MTL - operator=* tag </div><div><br></div><div>You should write down all these transformation rules on the import page.</div><div>If you are not sure about which OSM tags to use for a particular type of bike lane, you should check with local mappers. In Ottawa for that purpose, we compiled a local wiki: <a href="https://github.com/BikeOttawa/OSM-Bike-Ottawa-Tagging-Guide" target="_blank">https://github.com/BikeOttawa/OSM-Bike-Ottawa-Tagging-Guide</a> For Montreal most tags should be the same I suspect.</div><div><br></div><div>As for the technical part of the import, I would use task manager to split the city into more manageable chunks: <a href="http://tasks.osmcanada.ca/" target="_blank">http://tasks.osmcanada.ca/</a> </div><div>You'll definitely need to go through every segment you are importing manually one-by-one and make sure you fix all JOSM warnings on upload.</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jul 6, 2020 at 10:42 AM Matthieu Guyonnet-Duluc via Imports <<a href="mailto:imports@openstreetmap.org" target="_blank">imports@openstreetmap.org</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>Hello,<div><br></div><div><div style="margin:0px;font-stretch:normal;font-size:13px;line-height:normal;font-family:"Helvetica Neue"">The City of Montreal (Quebec, Canada) is expanding rapidly the bike lanes network and has an open data website where this network is available as GeoJSON and KML files (<a href="https://donnees.montreal.ca/ville-de-montreal/pistes-cyclables" target="_blank"><span style="color:rgb(220,161,13)">https://donnees.montreal.ca/ville-de-montreal/pistes-cyclables</span></a>).</div></div><div><br></div><div><div style="margin:0px;font-stretch:normal;font-size:13px;line-height:normal;font-family:"Helvetica Neue";color:rgb(220,161,13)"><span style="color:rgb(0,0,0)">I have started a page for this project here <a href="https://wiki.openstreetmap.org/wiki/Import_Project_:_Montreal_Bike_Lanes_Network" target="_blank">https://wiki.openstreetmap.org/wiki/Import_Project_:_Montreal_Bike_Lanes_Network</a> </span></div></div><div style="margin:0px;font-stretch:normal;font-size:13px;line-height:normal;font-family:"Helvetica Neue";color:rgb(220,161,13)"><span style="color:rgb(0,0,0)"><br></span></div><div style="margin:0px;font-stretch:normal;line-height:normal"><font face="Helvetica Neue" size="2">In the past, I have done some small and manual edits in OSM with JOSM but I’m not familiar with geospatial tools and data.
