Part 5: Route Visualization UI with Mapbox & Deck.gl

Rendering a single route on Google Maps is trivial. Rendering 100,000 historical vehicle routes, Origin-Destination matrices, and dynamic H3 geofences simultaneously? That requires offloading computation from the browser’s CPU to the GPU using WebGL. Answer-first: Do not use native Mapbox GL JS to render massive, dynamic datasets. Modifying the DOM or standard Mapbox sources with thousands of updates per second will freeze the browser. The industry standard is to use deck.gl paired with MapboxOverlay. This allows Deck.gl to render raw data directly onto the GPU while perfectly synchronizing with Mapbox’s camera. ...
