Pre-defined sets of metrics

Description

Pre-defined sets of point cloud metrics composed of different metrics_* functions available in the package.

Usage

metrics_set1(
  z,
  zmin = NA,
  threshold = c(2, 5),
  dz = 1,
  interval_count = 10,
  zintervals = c(0, 0.15, 2, 5, 10, 20, 30)
)

.metrics_set1

metrics_set2(
  z,
  ReturnNumber,
  NumberOfReturns,
  zmin = NA,
  threshold = c(2, 5),
  dz = 1,
  interval_count = 10,
  zintervals = c(0, 0.15, 2, 5, 10, 20, 30),
  KeepReturns = c(1, 2, 3, 4)
)

metrics_set3(
  x,
  y,
  z,
  i,
  ReturnNumber,
  NumberOfReturns,
  zmin = NA,
  threshold = c(2, 5),
  dz = 1,
  interval_count = 10,
  zintervals = c(0, 0.15, 2, 5, 10, 20, 30),
  pixel_size = 1,
  vox_size = 1,
  KeepReturns = c(1, 2, 3, 4)
)

.metrics_set3

Arguments

`zmin`	Minimum height. If set, heights below are ignored in calculations.
`threshold`	Threshold height(s). See metrics_percabove.
`dz`	layer thickness to use when calculating entropy and VCI.
`interval_count`	Number of intervals used to divide the point height distribution. See metrics_canopydensity.
`zintervals`	Height intervals. See metrics_interval.
`ReturnNumber`	return number
`NumberOfReturns`	number of returns
`x`, `y`, `z`	X, Y, Z coordinates of the point cloud
`i`	Intensity
`pixel_size`	pixel size for calculating rumple index
`vox_size`	voxel size for calculating voxel metrics

Format

An object of class formula of length 2.

Details

The three pre-defined sets of metrics include different number of the metrics_* functions and are provided to conventiently compute most of the metrics commonly used at the same time.
