About This Project

The 30 Day Map Challenge is a daily mapping initiative that runs throughout November. Each day features a different theme, encouraging cartographers, GIS professionals, and data enthusiasts to create and share unique visualizations.

All maps on this page are built with modern web mapping technologies including Mapbox GL JS, GeoJSON data formats, and responsive design principles. Each map is fully interactive and includes downloadable data for further exploration.

Technologies Used

  • Mapbox GL JS for interactive mapping
  • PostgreSQL/PostGIS for spatial data management
  • Python for data extraction and processing
  • GeoJSON for web-compatible spatial data
  • Responsive design for all devices
