Long-term video surveillance and automated analyses of hibernating bats in Virginia and Indiana, winters 2011-2014.
This data release includes video files and image-processing results used to conduct the analyses of hibernation patterns in groups of bats reported by Hayman et al. (2017), "Long-term video surveillance and automated analyses reveal arousal patterns in groups of hibernating bats. Thermal-imaging surveillance video cameras were used to observe little brown bats (Myotis lucifugus) in a cave in Virginia and Indiana bats (M. sodalis) in a cave in Indiana during three winters between 2011 and 2014. There are 740 video files used for analysis (Analysis videos), organized into 7 folders by state/site and winter. Total size of the video data set is 14.1 gigabytes. Each video file in this analysis set represents one 24-hour period of observation, time-lapsed at a rate of one frame per 30 seconds of real time (video plays at 30 frames per second). A folder of illustrative videos is also included, which shows all of the analysis days for one winter of monitoring merged into a single video clip, time-lapsed at a rate of one frame per two hours of real time. The associated image-processing results are included in 7 data files, each representing computer derived values of mean pixel intensity in every 10th frame of the 740 time-lapsed video files, concatenated by site and winter of observation. Details on the format of these data, as well as how they were processed and derived are included in Hayman et al. (2017) and with the project metadata on Science Base.
