This repository contains my self-collected event data for the Roland Garros 2022 Quarter Final Match between Novak Djokovic and Rafael Nadal.

A writeup of this data collection experience, and a data visual-heavy report of the above match can be read on my blog here, containing figures like this!

15. Shot_Type: Indicates the type of shot played e.g. 1st Serve, Topspin, Slice.
16. X: The x-coordinate (in meters) of the shot contact location (ball-racket), measured from the centre of the court (0,0).
17. Y: The y-coordinate (in meters) of the shot contact location (ball-racket), measured from the centre of the court (0,0).
18. X2: The x-coordinate (in meters) of the shot bounce location (unless no-bounce is mentioned in the "Remarks" column), measured from the centre of the court (0,0).
19. Y2: The y-coordinate (in meters) of the shot bounce location (unless no-bounce is mentioned in the "Remarks" column), measured from the centre of the court (0,0).
20. Outcome: The shot outcome e.g. Winner, Forced-Error, Fault, In-Play.

Unfortunately, I did not manage to record the time or frame count in this project.

Court Orientation

The data has been scaled and shifted from its original coordinates into a 1:1 scale with (0,0) defined as the centre of the court. Not transformation has been applied to standardise the hitting/bounce/player sides yet i.e. plotting the data as it is should resemble the source broadcast view.

Notebook

A simple notebook.ipynb has been written to get you started on producing visuals from this data.

Errata

There are bound to be errors in the data due to the method of collection, my own judgement and carelessness (e.g. forgotting to change shot tags). Feel free to raise an issue if there are any shot(s) that you find, significantly deviated from reality.

My recording of the serve contact Y locations also wavered throughout due to me doubting where the ball tosses are and changing my mind a couple of times. I suggest you don't conduct any substantial analysis on the serve contact point locations.
