misc-over: Find spatial join or intersections

In rgeos: Interface to Geometry Engine - Open Source ('GEOS')

Find spatial join or intersections

Description

Find spatial join or intersections

Usage

overGeomGeom(x, y, returnList = FALSE, fn = NULL, ..., minDimension = -1)
overGeomGeomDF(x, y, returnList = FALSE, fn = NULL, ..., minDimension = -1)

Arguments

x	see over
y	see over
returnList	see over
fn	see over
...	see over
minDimension	integer; if -1, gIntersects is used to find geometry intersections; if 0, 1 or 2, gRelate is used. if gRelate is used, intersecting geometries are ordered by the dimension of the intersection (2: area overlap; 1: line in common; 0: point in common), and minDimension determines the mininum dimension of intersection required.

Value

see over

Note

gRelate (minDimension > -1) is likely to be substantially slower than gIntersects.

Examples

p1 = readWKT("POLYGON((0 1,0.95 0.31,0.59 -0.81,-0.59 -0.81,-0.95 0.31,0 1))")
p2 = readWKT("POLYGON((2 2,-2 2,-2 -2,2 -2,2 2),(1 1,-1 1,-1 -1,1 -1,1 1))")

overGeomGeom(p1,p2)
