Some performance analysis for GraphHopper maps using mapbox and openlayers

Instructions

1. Start GraphHopper (v2.0 should do). Feel free to adjust or remove zoom limits of GraphHopper's /mvt endpoint or checkout https://github.com/easbar/graphhopper/releases/tag/gh_maps_experiments_v1
2. Open one of the index.html files in your browser

Features

• Experiments for Mapbox GL JS and OpenLayers
• Render the map using Raster or Vector Tiles
• Render GraphHopper graph using /mvt endpoint
• Render the shortest path tree for a given time-radius
• Mapbox only: Render isochrones for a given time-radius
• Mapbox only: Use deck.gl to render the shortest path tree or ischrone
