osmosis schema, style with OSM-Bright

Question

I have used Osmosis to load a large cut of OSM into a PostGIS DB, that works great. BUT, I would like to use the OSM-Bright style (carto CSS) to style it in TileMill and built tiles, offline. Going through the OSM-Bright user guide/install etc. there is no option to configure it to use an Osmosis schema (only osm2pgsql and imposm).

On windows osm2pgsql will not import very large OSM datasets hence the Osmosis route to get me this far.

Is there a way to style my data imported with Osmosis, or modify my DB so it is in the correct schema (the schema osm2pgsql uses)?

Answer 1

Osmosis stores the OSM data in the same way as the editor uses it: nodes, ways and relations.

One of the time consuming tasks of osm2pgsql is to convert closed ways and multipolygon relations to multipolygons that can be used for rendering, as well as defining a rendering order of features that overlap like bridges over ways or other buildings. This is not done by osmosis, and doing that manually will be quite a pain.

What you can do:

• Cut the large OSM dataset with osmfilter or osmconvert in smaller, overlapping rectangles, and render those one after each other
• install Oracle virtual box with a current Ubuntu, and render the tiles inside the virtual box
