In plain words
This project provides code to generate large-format custom Google Maps for printing and wall display. Users can map locations they've explored in their city on a 25000 x 25000 pixel image. The Python-based tool uses browser automation and image processing to create the map, which can be printed and displayed as wall art. Materials cost approximately $50, with generation and printing taking roughly 75 minutes total.

It uses the Selenium library for browser automation, and the Pillow library for image manipulation. The main script is only 132 lines long, 40 of which are comments, if you want to check it out for yourself. The build was…from roche.io
