A closer look

After a historic fire season, I wanted to see how fire detections were spread across the state.

Each hexagon covers about 250 km² and rises with the number of satellite hotspot detections inside it, up to 26,643 in a single cell. I first built the map with deck.gl for the challenge. This interactive version uses MapLibre’s 3D extrusions, with hotspot data from OroraTech.

Interactive view

Tilt and zoom across the state, point at a hexagon for its count, or switch to a flat view.
