Mapbox - invalid tile order
I am working on my own tile server. I have weird problems with displaying tiles in the correct order. Tiles were created using OSM data. When I use tileserver-gl-light as a tiles server everything seems to be ok, but when I try to serve tiles by my own server they do not appear in correct order after zooming. I use the same page to render the map so I think the problem is connected with the server. The tiles look like this (Zoom 1):
I appreciate any help. Best regards, Marek
I don't know the reason why but there was a need for correction y axis value before fetching data from mbtiles database.
If your tiles url looks like: http://host:port/data/{z}/{x}/{y}
you need to recalculate y value before fetching tile data in pbf format from database:
y = pow(2, z) - 1 - y
There is no mention about this in mbtiles specification but I found the solution in Tileserver-PHP source code
