A complete set of WMO weather symbols in SVG with full metadata
The full repository sources are available at https://github.com/OGCMetOceanDWG/WorldWeatherSymbols.git
A set of pre-generated PNGs are available for download at https://github.com/OGCMetOceanDWG/WorldWeatherSymbols/releases/download/0.6.0/WorldWeatherSymbols-0.6.0-png.zip.
To build PNG equivalents of the symbols, run ./scripts/wws_manage.sh png. Output PNG files are located in png/. Inkscape is required to run the conversions.
A list of symbols with their filenames and associated descriptions is provided in symbols subfolders in the respective README.md files (example for the Ft_Fronts subfolder). Those README.md files are generated automatically by the wws_manage.sh script. These lists act a short guides to the WMO WorldWeatherSymbols.
WorldWeatherSymbols can be displayed directly on Github either by opening the symbol's svg file or by using RawGit to include symbols in Markdown-formatted files, example:
