Simplifies LineStrings, Polygons, and their Multi- counterparts.
Usage
simplify_geoms(x, epsilon)
simplify_vw_geoms(x, epsilon)
simplify_vw_preserve_geoms(x, epsilon)Arguments
- x
an object of class of
rsgeo- epsilon
a tolerance parameter. Cannot be equal to or less than 0.
Details
Simplify functions use the Ramer–Douglas–Peucker algorithm. Functions with vw use
the Visvalingam-Whyatt algorithm.
For more see geo docs.
