three-geo is a three.js-based geographic visualization library that builds satellite-textured 3D terrain models in near real-time from GPS coordinates. It uses RGB-encoded DEM tiles from the Mapbox Maps API and exposes terrain as standard THREE.Mesh objects for GIS experimentation in JavaScript.

Use cases

• build 3D terrain models from GPS coordinates
• visualize satellite-textured terrain in the browser
• measure distances between points on 3D terrain
• run GIS experiments on terrain mesh geometry in JavaScript
• render elevation contours over 3D landscapes
• project a camera position onto a Leaflet map in real time

When to choose

• you need quick 3D terrain visualization from lat/lng coordinates in a web app
• you want terrain as standard three.js meshes for custom analysis or rendering
• you're already using three.js and Mapbox services

When to avoid

• you need a full GIS desktop application
• you can't rely on the Mapbox Maps API for DEM and satellite imagery
• you need global-scale terrain streaming rather than small region tiles
