Shipping Lanes

General talk
1

I’ve noticed that in the OSM base layer there are shipping lanes leading to/from major seaports. I’m interested in downloading the data for these shipping lanes via the overpass API.

Here’s an example of the shipping lanes I’m talking about: http://www.openstreetmap.org/#map=15/41.3529/2.1906

http://wiki.openstreetmap.org/wiki/Marine_navigation#Ferry_and_shipping_routes suggests shipping lanes are marked with seamark:type=separation_boundary, seamark:type=separation_zone and seamark:type=separation_lane.

I used the following query to overpass

 http://www.overpass-api.de/api/xapi?*[bbox=-180,-90,180,90][seamark:type=separation_lane]

, as well as queries for separation_boundary and separation_zone. However, the data returned does not correspond to the shipping lane data I see in the OSM base layer.

I have also read through much of the information on openseamap.org to no avail. Any guidance would be much appreciated.

It looks like this mapping is not in widespread usage: https://taginfo.openstreetmap.org/tags/seamark%3Atype=separation_lane#overview

Check overpass turbo: https://overpass-turbo.eu/?w=%22seamark%3Atype%22%3D%22separation_lane%22+global&R (again, please try to avoid XAPI, it’s outdated)

Also, try the “?” (question mark symbol) on osm.org to inspect the actual data at a location, or use your favorite OSM editor (iD, JOSM, Potlatch) to inspect the respective data.

Thank you. Using the query tool on osm.org, I was able to determine that they are ferry routes and not shipping lanes as I had supposed.
