This repo contains the forks of the following styles:
Bright - forked from https://github.com/openmaptiles/osm-bright-gl-style
Liberty - forked from https://github.com/maputnik/osm-liberty
Positron - forked from https://github.com/openmaptiles/positron-gl-style
Dark - forked from https://github.com/openmaptiles/dark-matter-gl-style
All the OpenMapTiles styles (Bright, Positron, Dark) are abandoned by their upstream project. Liberty is fresh and alive.
The long term goal of this project is to maintain a consistent style across these forks. The plan is to split the styles to building blocks (like road layers, etc.) and build up new styles from these blocks.
Work is being done to make Bright, Liberty and Positron consistent.
Most of the work so far has been done in these areas:
- all labels and text fields (water, roads, cities)
- country and administrative borders
- POIs
Positron, as a special clean looking style, has POIs removed and some highway labels set to show at higher zooms only.
Dark is currently put on hold, it's very different from the rest. A better approach would be to try to invert Positron in a fitting color space.
Part of this repo is a compare styles web app. Currently it works on localhost, but in the future there'll be a web hosted version with a nicer GUI. The point of compare is to compare different styles and different data sources.
- lint_styles.py - removes unnecessary keys, runs gl-style-migrate, does recursive JSON sorting, outputs using gl-style-format and runs gl-style-validate
- lint.sh - does this for the whole repo, it should be used before every PR
- copy_text_fields.py - copies all text fields from a source style to a destination style (and removes existing ones)
- fix_text_fields.py - sets OpenFreeMap specific values in styles
Most tools used work on recent node versions, but fonts and sprites use tools which require node 12.
