Nebra Shot Maps

Matching constellations to shot maps.

Run make all to run the matching algorithm for all constellations and view the results at data/constellations/{constellation}/..., after making sure you've satisfied the requirements (listed below).

Alternatively, you can download a sample of matched constellations and shot maps from the releases.

Requirements

• A Python environment (assumed to be at venv, unless otherwise set with the PYTHON_VENV environment variable). Anything version 3.6+ should be fine. Required packages are in requirements.txt.
  • You can create a virtual environment at venv and install the requirements with make venv
• An R installation, with the tidyverse and ggsoccer installed. I used v3.6.3 (I haven't tested v4, but I assume that's fine, too)
• data/shots.csv. I used a csv with the following columns, one row per shot (I think fbref publishes this data now, so you should be able to get it from there). Fields that aren't used by the main algorithm are shown in square brackets. Skipping these columns won't matter, but will result in a warning message. (There is a make rule for data/shots.csv that you can replace should you want to.)
