From: Dead-reckoning animal movements in R: a reappraisal using Gundog.Tracks

Fig. 2

Schematic of the conceptual workflow involved when dead-reckoning using Gundog.Tracks—elaborated within “VPC dead-reckoning procedure in R” section. Note Gundog.Peaks (Additional file 3) is a peak finder function that locates peaks based on local signal maxima and Gundog.Compass (Additional file 2) is a function to correct iron distortions from tri-axial magnetometry data and subsequently compute tilt-compensated heading. Both functions are elaborated within “VPC dead-reckoning procedure in R” section and in Additional file 1. The direction of workflow and key questions asked follow from green—(pre-processing and data alignment) to purple—(computing heading) sections, before splitting into blue—(air/water) and brown—(land) sections (computing speed) and culminating at the red section (final pre-dead reckoning checks/data formats and post-dead-reckoning checks/plots) in conjunction with the process of using Gundog.Tracks in R (yellow)
