Data and Documentation

  The dataset combines 3D goalie pose with puck position and velocity, synchronized frame by frame. SPL's supplied documentation describes 81 shots from one goalie (P0001), recorded August 6, 2026, at 60 Hz.

Data and Supporting Materials

The full dataset release is forthcoming in SPL-Open-Data. The file below is one sample shot, not the full dataset.

Shot files are organized by session and participant, for example data/2026-08-06/P0001/HK_GL_P0001_S0001.json. Participant IDs remain consistent across sessions; shot IDs increase chronologically within a session.

Coordinate System and Units

Positions use [x, y, z] in feet, with the origin at center ice. Positive x points toward the goal used in this session, whose goal line is at x = 89 feet. Positive y is upward in the diagram; positive z is above the ice, with z = 0 at the ice surface. Velocity components use feet per second.

Processing, Alignment, and Missing Values

According to SPL's README, goalie keypoints were smoothed using a robust Savitzky–Golay filter (third-order polynomial, 11-frame window). Each goalie frame is matched to the closest puck measurement within 8 milliseconds; puck values are not interpolated. A null value means an observation is unavailable; it is different from [0, 0, 0]. Puck detections can be absent when the puck is occluded or outside the camera view. Preserve the supplied observations and document any interpolation, filtering, or reconstruction you perform.

Orientation Video

This short video shows shot S0011 reconstructed from tracking data alongside overhead, bench-wall, and stands-wall camera views. It provides context for the tracking; it is not a release of the full session videos. Open or download the orientation video

 

Shot Animation

  SPL plans to include animation code with its repository release. The original README describes animate_shot() and camera options. That script is not included in this sample download.
