Perimeter or length — perim • terra

This method returns the length of lines or the perimeter of polygons.

When the crs is not longitude/latitude, you may get more accurate results by first unprojecting the SpatVector (you can use project to transform the crs to longitude/latitude)

Usage

# S4 method for SpatVector
perim(x)

Arguments

x: SpatVector

Value

numeric (m)

Examples

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
perim(v)
