During March 2026, Jonathan Feddersen focused on improving geospatial rendering accuracy in the maplibre-gl-js repository by addressing a critical bug in globe projection. He fixed the distance-to-tile calculation when the query point lies to the right of the tile, a scenario that previously caused visual discrepancies in globe mode. Using TypeScript and leveraging strong geospatial analysis skills, Jonathan expanded the test suite to cover various bearings at high elevation and pitch, ensuring projection accuracy under challenging conditions. His work demonstrated careful attention to mathematical detail and test-driven development, resulting in enhanced rendering fidelity and stability for globe projection features.
