tagtools - Work with Data from High-Resolution Biologging Tags
High-resolution movement-sensor tags typically include
accelerometers to measure body posture and sudden movements or
changes in speed, magnetometers to measure direction of travel,
and pressure sensors to measure dive depth in aquatic or marine
animals. The sensors in these tags usually sample many times
per second. Some tags include sensors for speed, turning rate
(gyroscopes), and sound. This package provides software tools
to facilitate calibration, processing, and analysis of such
data. Tools are provided for: data import/export; calibration
(from raw data to calibrated data in scientific units);
visualization (for example, multi-panel time-series plots);
data processing (such as event detection, calculation of
derived metrics like jerk and dynamic acceleration, dive
detection, and dive parameter calculation); and statistical
analysis (for example, track reconstruction, a rotation test,
and Mahalanobis distance analysis).
