Generate static tiles with current OSM style from PostGIS

Question

I'm trying to generate static tiles for Great Britain with the current OSM style. I have populated my PostGIS database from a osm.pbf file from here [1]. I have Mapnik version 3.0.9 installed.

I can generate tiles using the polytiles.py script from [2] but they use the old OSM styles. The polytiles.py script only accepts xml style sheets but the new OSM styles are not xml [3].

Is there another script I can use instead of polytiles.py to do the same thing?

Answer 1

I got it working using the following steps...

1. Install Carto with the following command... npm install carto
2. Convert the CartoCSS-based stylesheets to XML using carto project.mml > osm.xml
3. Pass the new osm.xml file as an argument to polytiles.py.
