Correct Return Reflectance based on Distance using Xu et al. 2017

Description

This function takes a LAS input containing the fields Amplitude in dB and Distance in meteres. It applies a distance based correction using the methods of Xu et al. 2017. The formula only applies the correction based on distance, but not incident angle. The study used a REIGL VZ400i, but less sure if this applies to other scanners.

Usage

correct_Reflectance_Xu2017(las)

Arguments

las	a LAS object containing attributes for Amplitude and Distance

Examples

## NOT RUN ##
#las = readLAS('las1.laz')
# corr = correct_Reflectance_Xu2017(las)
# par(mfrow = c(1,2))
# plot(las$Amplitude ~ las$Distance)
# plot(corr, las$Distance)
