In TrackReconstruction: Reconstruct Animal Tracks from Magnetometer, Accelerometer, Depth and Optional Speed Data

Description

Raw data file from a northern fur seal with date, time, internal temp, depth, triaxial magnetometer, accelerometer, and wet/dry fields. This data set is bookended by the first 7 gps points in the gpsdata02 data set and is used in the examples for the DeadReckoning, GeoReference, GraphLimits, Splitter and GeoRef functions.

Usage
