sharedstreets.tile.get_tile doesn't get dedicated infraestructure for buses like BRT in Buenos Aires

[alephcero]

I'am running Python 3.6.5
Using the python library on Buenos Aires City with sharedstreets.tile.get_tile(12, 1383, 2468) I get

There you can see Metrobus Network (Buenos Aires BRT) is missing in the geometries.

While in you online map you can see it loaded to sharedatreets network
https://platform.sharedstreets.io/-34.62128/-58.37974/16.467/

The OSM tag on the Metrobus BRT shows access=no, bus=yes as specified in the OSM docs

Thanks for the report! This might be related to the road class filter in the tiles we use? Can you try passing a different URL template to get_tile(), vs. the default in https://github.com/sharedstreets/sharedstreets-python/blob/master/sharedstreets/tile.py#L9

E.g. replace the 6 with a 7; if that fixes it then I’ll improve the documentation around this.

I used the following template:

tile = sharedstreets.tile.get_tile(12, 1383, 2468,data_url_template = 'https://tiles.sharedstreets.io/osm/planet-180312/{z}-{x}-{y}.{layer}.7.pbf')
It returns and empty collection:

{'type': 'FeatureCollection', 'features': [], 'references': []}

Using the following line in OSMNX i get those roads

point= (-34.620486, -58.380824)
G = ox.graph_from_point(point,distance=500,network_type = 'drive_service')

Hm, maybe that’s not the URL. @kpwebb do you have an index of URLs that I’m mis-remembering? Any updates on sharedstreets/sharedstreets-ref-system#20?

@alephcero and @migurski thanks for flagging this.

On the first point about metro bus segments, that's very likely a road class issue. Per Mike's point, "level 6" is currently clipping out roads unless they're "tertiary" or greater, or "unclassified". It's likely the busway doesn't meet that criteria.

At the moment we only have "level 6" tiles up on the tile endpoint, but we can add level 7 (service) and 8 (other). We're also in the process of adding a "level 9" for bike and ped infrastructure.

As a starting point I'll copy up the existing 7 and 8 tiles, and update this thread. I'm curious if that addresses the busway.

In case you're interested you can see how we define the levels here -- I'll move this into the reference spec documentation:

That's great news!

I'll wait for the updates and glad to help in this project!
