lasclip
Clip LiDAR points
Clip LiDAR points within a given geometry and convenient wrappers most common geometries
Usage
lasclip(.las, geometry, coord, inside = TRUE)lasclipRectangle(.las, xleft, ybottom, xright, ytop, inside = TRUE)
lasclipPolygon(.las, x, y, inside = TRUE)
lasclipCircle(.las, xcenter, ycenter, radius, inside = TRUE)
Arguments
- .las
An object of class
LAS- geometry
characters. name of a geometry. Can be
"circle","rectangle","polygon","cuboid"or"sphere"- coord
matrix or data.frame. The coordinates of the minimum points required to fully describe the geometry. For circle a 1-by-3 matrix, for rectangle a 2-by-2 matrix, for polygon n-by-2 matrix, for cuboid 2-by-3 matrix and for sphere a 1-by-4 matrix
- inside
logical. Keep data inside or outside the shape
- xleft
scalar. of left x position.
- ybottom
scalar. of bottom y position.
- xright
scalar. of right x position.
- ytop
scalar. of top y position.
- x
numerical array. x-coordinates of polygon
- y
numerical array. y-coordinates of polygon
- xcenter
scalar. x disc center
- ycenter
scalar. y disc center
- radius
scalar. Disc radius
Value
An object of class LAS
