The Package “sigloc” for the R Software: A Tool for Triangulating Transmitter Locations in Ground‐Based Telemetry Studies of Wildlife Populations

Abstract

Despite the advent of GPS collars and technology, a large portion of wildlife studies still relies on radio‐tracking to study the movement patterns, habitat selection, and space use of individual animals. I present here the “sigloc” package for the R software, which offers basic functions to analyze radio‐tracking data, methods to estimate the location of a VHF transmitter using azimuth bearings, and interfaces with other R packages and functions. These tools can be downloaded freely on the internet and provide a powerful environment for the analysis of radio telemetry data.
