The author created a tool called temsinal.org to map all cell towers in Brazil using data from ANATEL and IBGE. The backend consists of Python scripts that fetch data, process it, and generate map tiles with tippecanoe. The frontend displays the information on an easy-to-use map interface hosted via Cloudflare Pages and R2, allowing users to visualize tower density, age, and coverage improvements over time.
