Unwetter

Automatically notify newsroom about weather warnings from DWD

Map generation

The WDR Sans fonts, map design and source images are proprietary and not licensed under the MIT license. To make your own design, do the following steps:

1. Optional: Edit config.yaml to select the desired state(s)
2. Start a local development Flask instance using FLASK_APP=app FLASK_ENV=development pipenv run flask run
3. Navigate to http://127.0.0.1:5000/basemap to get a black/white map template
4. Use the template to create your own map design
5. Replace the files in assets/images
6. Replace the WDR Sans fonts in assets/fonts
7. Update the font import and drawing in src/unwetter/map.py:draw_text
