3D geospatial data visualization using Python and Cesiumjs
summary
Processes London TfL GeoJSON with Python + geopandas to produce colored underground-line polygons, then renders 3D buildings and lines on a Cesium globe using CesiumJS and a Cesium ion API token. The demo loads OpenStreetMap 3D tiles (buildings) with just a few lines of code, handles messy file and network hiccups during live processing, and is deployable as a static site (Netlify or GitHub Pages). The visualization works end to end.
