Simplify Geometry
Description
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 |
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.
Value
an object of class rsgeo
Examples
x <- geom_linestring(1:100, runif(100, 5, 10))
simplify_geoms(x, 3)
simplify_vw_geoms(x, 2)
simplify_vw_preserve_geoms(x, 100)
