I need to access to the Mapillary vector tiles (???) using Leaflet as they are shown in the Mapillary web site, for example
https://www.mapillary.com/app/?lat=44.90785153249567&lng=7.673778533935547&z=16
I've tried to use the Mapillary vector tiles API as documented here
http://blog.mapillary.com/update/2015/05/27/vectortiles.html
so using this request
https://d2munx5tg0hw47.cloudfront.net/tiles/{z}/{x}/{y}.mapbox
but I can see the vector tiles only for levels 0 - 14 not more, then I receive a 403 (Forbidden) error.
Are there alternative ways to obtain Mapillary vector tiles or how this issue is solved by the Mapillary web site?
Any link / suggestion / example?
UPDATE - 23/08/2016
===================
I don't have still the solution but I've some news that I hope can be useful to solve the problem.
I've found in the Mapillary Forum (ref. https://github.com/mapbox/osm-navigation-map/issues/48), that they are changing the url to access to the vector tiles.
The new url is the follow:
https://d25uarhxywzl1j.cloudfront.net/v0.1/{z}/{x}/{y}.mvt
with these specifications
- Endpoint: http://d25uarhxywzl1j.cloudfront.net/v0.1/{z}/{x}/{y}.mvt
- Extent: 4096
- mapillary-sequences Layer (Type Line)
- mapillary-images Layer (Type Circle)
So I've tried to load this new vector tile layer in a simply Leaflet 0.7 map using this code

You can view the map at this link
http://www.cesaregerbino.com/Mapillary/VectorTilesTest/testLeaflet.html
In the map there are both the "old" mapillary vector tiles (purple lines), and the "new" mapillary vector tiles.
It's working fine but unfortunately if you try to zoom in at more details nothing is mapped.
Searching on the web I've found this link
http://mapbox.github.io/osm-navigation-map/#6.09/44.391/8.984
that seems working fine as I'd like, so I've tried to replicate it and I've done it, here you are the code

In this map there is only the "new" mapillary vector tiles layer.
It's working fine too but unfortunately if you try to zoom out at less details nothing is mapped.
So it seems that the new mapillary vector tiles behaviour it's different if I use it in a Leaflet map or in a MapBox map.
I'd like to use it in a Leaflet (0.7) map but I need to see on the map the layer also when I'm in detailed map (zoom in ...).
These news can help to solve my troubles? I hope so!
