Map Tor relays using Cartopy

Create a map showing the geographic location of the Tor relays

Setup

1. Create a venv: python -m venv venv && source venv/bin/activate
2. Install requirements: pip install -r requirements.txt

Get the data to create the map

You'll need two files:

1. The Tor consensus you want to use. Download one at: https://metrics.torproject.org/collector/recent/relay-descriptors/consensuses/
2. The GeoLite2 City file from MaxMind (not the CSV format). See their website to create an account and get the file: https://dev.maxmind.com/geoip/geolite2-free-geolocation-data

Run the program

The program takes two arguments: the filename of the consensus and the filename of the GeoLite2 mmdb file.

python map.py 2024-03-27-13-00-00-consensus GeoLite2-City.mmdb

Optional parameters

--eps 1.5: control the density of the clusters. The default is 1.5 and generally gives nice maps. The higher the value, the bigger the clusters.

--weight: if set, use the consensus weight instead of the count of relays for the size of the clusters.

python map.py 2024-03-27-13-00-00-consensus GeoLite2-City.mmdb --eps 1.5 --weight

Using OSM data (optional)

It is possible to use data from OpenStreetMap as background (instead of the default cartopy image).

Check the code and the TODO comment to enable that. If you use OSM data and Mapbox as suggested in the comment, please use attribute it properly.

The following attribution line is generally enough:
