An application programming interface for analysing and visualising data generated from the VEMCO suite of passive acoustic receivers
V-Track is a collection of R functions designed to enable storage, analysis and visualisation of detection data from the VEMCO suite of receivers and transmitters.
V-Track will assimilate acoustic transmissions derived from the VEMCO suite of continuous and coded tags and detected by the VR2, VR2-W and VR100 receivers.This enables the user to process data from both passive and active acoustic telemetry within a central database. Archived acoustic data stored within the Australian Animal Tagging and Monitoring System (AATAMS) database can also be processed and visualised using the V-Track software.
V-Track consists within a sequential modular format, the routine steps for the processing of the acoustic detection data are:
1. Archiving of the detection database
2. Creation of sub-archives based upon study parameters
3. Creation of a distance matrix using direct or circuitous distances between receivers
4. Identification of animal behavioural events within the detection sub-archives
5. Organisation behavioural events by temporal conditions
6. Visualisation of animal movements through time using Google Earth
A graphical user interface (GUI) for V-Track is also available to download. This contains the same analysis tools as the R package but requires no prior knowledge of R.
On running each of the functions in the V-Track GUI, a text file is returned containing the R code used in each step. This helps the user to learn the V-Track R package which will offer user greater flexibility, error-checking capacity, figure generation and greater processing power.
What an awesome package! You saved me a massive amount of work! Philip Harrison PhD student, University of Waterloo, Canada
Thanks for developing such a great product as V-Track. And it’s great you guys have made it free! Bernie Cockayne, Water Scientist, Department of Natural Resources, Australia.
