Description

Return points at specified distances along a line.

Usage

gInterpolate(spgeom, d, normalized = FALSE)

Arguments

spgeom

SpatialLines or SpatialLinesDataFrame object

d

Numeric vector specifying the distance along the line geometry

normalized

Logical determining if normalized distances should be used

Value

SpatialPoints object

Details

If normalized=TRUE, the distances will be interpreted as fractions of the line length.
