sdc: Height Intervals of the Bearing Area Curve

In geodiv: Methods for Calculating Gradient Surface Metrics

Height Intervals of the Bearing Area Curve

Description

Determines the height interval (height distance) for points along the bearing area curve as defined by their x values.

Usage

sdc(x, low, high)

Arguments

x	A raster or matrix.
low	Numeric value along the x-axis corresponding to the lowest value of interest along the x-axis.
high	Numeric value along the y-axis corresponding to the highest value of interest along the x-axis.

Value

A numeric value of the difference in height of the y values along the bearing area curve corresponding to the specified x values.

Examples

# import raster image
data(normforest)
normforest <- terra::unwrap(normforest)

# determine the 10-40% height interval of the
# bearing area curve
val <- sdc(normforest, 0.1, 0.4)
