Local positioning system (LPS) sensors were deployed on indoor dairy cows (c100) to track their location and activity. The sensors continuously recorded locations every 8 seconds and activity every 10 minutes. Temperature-humidity index (THI) was also continuously recorded around the barn every 10 minutes (from n = 16 temperature-only sensors and n = 20 humidity sensors). 

From these recordings, various metrics were calculated: mean time spent near key resources and in the feeding zone, mean and variance in activity, mean z value (recorded from the LPS), mean distance travelled during high activity, and the mean and variance of four bunching metrics (range size, inter-cow distance and nearest neighbour distance). These summary metrics are provided for each four-hour time period throughout the study duration.
