simplifyGeom geometries
Reduce the number of nodes used to represent geometries. methods
## S4 method for signature 'SpatVector' simplifyGeom(x, tolerance=0.1, preserveTopology=TRUE, makeValid=TRUE)
x
: SpatVector of lines or polygonstolerance
: numeric. The minimum distance between nodes in units of the crs (i.e. degrees for long/lat)preserveTopology
: logical. If TRUE
the topology of output geometries is preservedmakeValid
: logical. If TRUE
, makeValid
is run after simplification to assure that the output polygons are validSpatVector
