Understand the Projection Tradeoffs
Learn what azimuthal projections preserve, why distortion grows away from the center, and when equal-distance or equal-area behavior is the right choice.
Read the Projection GuideExplore the world of map projections, learn cartographic techniques, and discover how different perspectives can change the way we see our planet.
Start With the Right Guide
This library is organized around practical map-making questions. If you are new to azimuthal maps, begin with the reading guide and projection comparison. If you want to build your own maps, use the Python or D3.js tutorials. Each article is written to connect the math of map projections to a working map you can inspect, modify, or generate yourself.
Apply Azimuthal Maps to Real Problems
See how center-based maps support radio bearing charts, route maps, classroom demonstrations, polar views, and statistical map design.
