This directory contains all SVG based symbology used in the style. The point symbols are mostly based on work done by OSM-Carto developers, the polygon and line patterns are mostly specific designs made for the AC-Style.
Most of the symbols are processed by python scripts into the version actually used for rendering.
Details on this can be seen below. The scripts also produces a contact sheet with previous of the symbols processed which can be found below.
The point symbols are processed with a script (/scripts/generate_symbols_labels.py) that colorizes the symbols and generates the SQL/MSS code for the POI layer. The whole process is described in this blog post.
Symbol sources can be found in the sources/ subdirectory, the definition of colors and rendering parameters in symbols-labels.yaml
Addon symbols for augmenting other point symbols are rendered directly from their SVG sources. These can be seen in preview here:
Single symbol patterns are rendered directly from SVG files. They are currently used for indicating the type of sport on leisure=pitch, parking spaces and some building types. Here are uncolored previews of the symbols used:
The line pattern SVGs are processed with (/scripts/generate_line_patterns.py) based on parameters in line_patterns.yaml
The polygon pattern SVGs are processed with (/scripts/generate_patterns.py) based on parameters in patterns.yaml
The unpaved road pattern SVGs are processed with (/scripts/generate_unpaved_patterns.py) based on parameters in unpaved_patterns.yaml
