Global Geospatial Point Data Visualiser

Web app built with TypeScript, React, Node.js (Express), Leaflet and Three.js. It renders large-scale point datasets on an interactive 2D map and 3D globe, allowing spatial patterns to be identified between them.

The app automatically processes GeoJSON Point features and is specifically designed for discrete geographic location data, where each point represents an actual place on Earth's surface.

The 2D view is a Leaflet based interactive map with Mercator projection point overlay. The 3D view is a Three.js sphere with an equirectangular surface map and point texture derived from the Leaflet view. The tileset used is provided by CARTO but any supported tileset could be mapped to the globe via this method.
