unable to render boundary/admin layer #1999

Open mkandulavm opened 5 years ago

mkandulavm commented 5 years ago

Hi

I have followed this article to extact MVT files from OSM PBF files. https://blog.jawg.io/how-to-make-mvt-with-postgis/

In their example using the browser mapbox renderer, the buildings (polygon), ameneties (POI) and admin (linestring) are visible.

I am using the same MVT tiles and trying to view with tangram-es. I have attached the scene file I am using. scene.zip

I modified the layer name in the scene file from pois -> ameneties and boundaries -> admin to match with the data in tiles.

In tangram-es, I am able to see the buildings (polygon) and ameneties (POI). However the admin (linestring) is not visible. Can someone please help me identify what I need to modify in the scene file so the admin layer is visible ?

Thanks.

Hi @mkandulavm! I think I understand what you're doing here, this is a cool idea. The scene file you attached doesn't have any obvious problems that I can see. Can you see if there is any error output in the console from Tangram ES?

Thanks for the reply @matteblair ! I could not find anything useful in the log. I am attaching it. There is only tile not found error, but those are for tiles that are not generated.

Is there a more detailed or verbose flag for logging ?

Could you give me some suggestions to explore how to find the problem ? Basically it looks like I am missing something to map in the scene file or something by default is overriding the display (zoom, filter?) to see the admin linestrings.

HI @matteblair , any help please ?

Hey, thanks for your patience with this! I don't see anything suspicious in the logs, now I'm wondering if the issue is something about the tile data instead. Do you have sample data containing boundaries that you can share?

Hi @matteblair

I am attaching sample tiles at zoom 15 and 16 for a small region of paris. tiles.zip

HI @matteblair

Could you suggest some debugging tips or where in the code I can start probing? :)
