The R package for analysing and visualising data generated from the VEMCO suite of passive acoustic receivers
V-Track contains a number of tools for analysisng your passive acoutic detection data. The routine steps for processing data are:
1. Archiving of the detection database
2. Creation of sub-archives based upon study parameters
3. Generate summary tables based on transmitter or receiver data
4. Creation of a distance matrix using direct or circuitous distances between receivers
5. Identification of animal behavioural events within the detection sub-archives
6. Organise behavioural events by temporal conditions
7. Visualisation of animal movements through time using Google Earth
This updated version (Version 1.11) features new visualisation tools, summary tables and compatability with R > v3.0.0.
To download and install V-Track, simply follow these steps:
1. Connect to the internet
2. Open R
3. Type the following code into your R console
If successful, this should now have installed VTrack to your Windows, Mac or Linux machine.
To load the software and access the reference manual, type the following code into your R console:

For more information see our V-Track publication in Marine and Freshwater Research or other listed publications which have used V-Track to analyse detection data from the VEMCO suite of receivers and transmitters.
There are also teaching materials for V-Track: V-Track, R and the Analysis and Visualisation of Animal Telemetry Data. This course was run by Ross Dwyer at the Sydney Institute of Marine Sciences in 2014. The workshop focused on the steps involved in processing, analysing and plotting acousic tracking data from fish and sharks using the R programming language and the V-Track R package.

Notes from our users
Just what I need to kick start me in an analyses of over 4 million hits from our acoustic array in the Caribbean, SP. NOAA, USA.
I found V-Track to be a fantastic tool, and I was able to use it to create all sorts of additional visualizations, from modeled salmon movement data to estuarine hydroacoustic biomass survey data. I greatly appreciated being able to open and edit output files, as that greatly added to V-Track's flexibility and allowed for such diverse uses. It has proven very useful to help in understanding this endangered species and its environmental interactions. Thank you again! KL. NOAA, USA.
