A function for estimating the User Equivalent Range Error (UERE) of a GPS device from calibration data.
Usage
uere(data,diagnostic=FALSE)
Arguments
data
Telemetry object or list of telemetry objects corresponding to calibration data with Movebank column GPS.HDOP.
diagnostic
Return extra details, such as the UERE's 95% confidence interval and a plot.
Value
Details
Often times GPS animal tracking devices return HDOP values but do not specifiy the device's UERE necessary to transform the HDOP values into absolute errors.
This function allows users to estimate the UERE from calibration data, where the device was left fixed over a period of time.
