In niknap/slidaRtools: Tools for lidar simulation and lidar processing

Convert a point cloud to a raster

Description

Function that creates a raster from a point cloud by applying a certain function in each cell, e.g. func=max returns a surface raster (CHM in case of vegetation), min returns lowest point per cell, mean returns the mean value of all points in the cell, count returns a point density raster, sum returns the sum of all point values and mode returns the most common value (in case of several equally common values one of them is taken randomly).

Usage

raster_from_point_cloud(
  pc,
  xcor = "X",
  ycor = "Y",
  var = "Z",
  res = 1,
  func = "max"
)

Arguments

pc	Point cloud in XYZ-table format
xcor	Variable name that contains the X-coordinates (Default "X")
ycor	Variable name that contains the Y-coordinates (Default "Y")
var	Variable name that contains the values that should be rasterized (Default "Z")
res	Resolution (cell side length) of the output raster
func	Function to be applied (either "max", "min", "mean", "count", "sum" or "mode")

Value

Raster object
