adjustedL: Adjusted Transect Length
In esbach/CurveTransect: Distance Sampling on Curving Transects
adjustedL R Documentation
Adjusted Transect Length
Description
Popular distance sampling packages automatically calculate the area covered in the survey based on a straight line, L x 2w, where L is the length of the transect and w is the truncation distance. This function calculates the the area covered in a curved transect and provides and adjusted transect length: curved covered area ÷ (2 × w). When input into popular distance sampling packages, this adjusted length will give the proper covered area.
Usage
adjustedL(transect, trunc)
Arguments
transect
GIS file of the transect of class SpatialLines
trunc
Truncation distance (meters)
Value
Length of the transect (meters) used by distance sampling packages to correctly calculate the covered area.
Examples
adjustedL(transect=transect, trunc=100)
