30 Day Map Challenge 2025
A daily mapping project exploring different cartographic techniques, spatial analysis methods, and data visualization approaches. Each map showcases unique datasets and interactive features using modern web mapping technologies.
Maps optimized for desktop viewing
Week 1: November 1-7
Projections
Alaska Distortion Comparison - 4 synchronized Mapbox GL JS maps showing Mercator, Albers, Equal Earth, and Winkel Tripel projections with live pixel measurements demonstrating how each projection distorts the same geography
Water
Classical Elements 4/4: Focus on the fluid. Map hydrology, oceans, currents, water accessibility, sea level rise, precipitation, or anything aquatic
Icons
Create a map where icons, pictograms, or custom symbols are the main focus. Use them to highlight points of interest or replace traditional cartographic features
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
