Note: util/example-frontend includes a slightly modified three-geo.

  • If using docker-compose, Redis Commander is available at http://127.0.0.1:8081
• node generatePixelCoords.js - Process and add util/example-depth-data.geojson to Redis
• Replace $YOUR_MAPBOX_TOKEN_HERE$ in hydroxy.js
• npm i && node hydroxy.js - Start proxy server
• cd util/example-frontend/dist && python3 -m http.server 80" - Serve example frontend
  • util/example-frontend/config.js contains some variables to play with (restart frontend after changing)
