See https://github.com/n129bz/chartmaker⁠ for details about this application

Chartmaker downloads FAA VFR and IFR digital raster charts and translates them into mbtiles databases for other mapping applications. The file /chartmaker/settings.json controls which charts to process, including zoom levels, image type to generate (png, jpg, or webp) etc.

Generated databases will be located in the /chartmaker/charts folder.

Take a look at my chart web server image at https://hub.docker.com/repository/docker/n129bz/chartserver for an example of an application that displays charts and much more!
