Analysis of data from tags with high-resolution movement-sensors presents many challenges, motivating development of software tools to facilitate analysis and interpretation. Led by a team including Lucía Martina Martín López, Stacy DeRuiter, Mark Johnson, René Swift, Tiago Marques, Catriona Harris, and others, this workshop introduces an open-source tool kit for analysis of data from tags with high-resolution movement sensors (such as pressure, accelerometer, magnetometer, gyroscope; sampled multiple times per second). The tool kit includes tools to read/write, calibrate, process, visualize, and statistically analyze datasets from multiple tag types, such as DTAG, Acousonde, CATS, Wildlife Computers, OpenTag, Little Leonardo and more.
