Running

Setting up Openrouteservice

• clone the openrouteservice repository
• To disable openrouteservice rate limiting, apply ./openrouteservice_config.patch to the sample config of the openrouteservice docker container.
• Download an appropriate open streetmap dataset (e.g. saxony)
• delete everything in docker/graphs! This will force openrouteservice to rebuild the map data. Otherwise, you might get unexpected Error Code 2099 errors, because the requested coordinates are off map. Running docker compose without the -d flag (in foreground mode) helps catch any out of memory exceptions.
• make sure the container has enough RAM available. Increase RAM limit as described in https://github.com/GIScience/openrouteservice/blob/master/docker/README.md. Using a VM with 3G of ram did not work for me, while 6G worked just fine.

Running locally

• Make sure you have openrouteservice running under localhost (follow https://github.com/GIScience/openrouteservice/blob/master/docker/README.md and load the dataset for saxony)
• Start the backend service: cd obst/tsopt/ && python3 optimize.py. It should load the pre-computed dataset graphs.
• Open the front-end file in obst/ui/index.html
