Video and Accelerometer Data for Oak Tree Sway in Wisconsin

Joseph Ammatelli from the University of Washington collected video and accelerometer data for a red oak tree in the Trout Lake Watershed, Wisconsin. The data includes five 60-second videos and continuous accelerometer readings recorded on 15 August 2019. Sway frequency data extracted from both sources is also provided.

Use Cases

• Analyzing tree sway frequency and dynamics based on video data.
• Comparing motion extraction methods (VVS vs. MBT) based on the sway frequency data.
• Validating accelerometer-derived sway measurements against video-based analysis.
• Studying the relationship between wind and tree movement based on time-series acceleration data.

Strengths

• Data includes five 60-second videos recorded at 30 fps and 1080p resolution.
• Accelerometer data was sampled continuously at 16 Hz.
• Sway frequency is provided from multiple extraction methods (VVS and MBT) and data segments (60-second and 30-minute).

Limitations

• Data is from a single tree on a single day, limiting generalizability.
• Column-level documentation for the raw data files is absent; field semantics must be inferred after download.
• Row count for the accelerometer and sway frequency data is unknown.
