I am trying to use lidR for the intensity normalization function it offers and I am consistently running into trouble. I have several different ALS datasets that I have tried with and am hoping to get some direction to figure out what is going wrong. I can provide sample .las files if needed.
Here is the code in RStudio:
library(lidR)
las1 <- readLAS("11SPS180600.las", filter = "-drop_withheld")
plot(las1, color = "Intensity")
las1 <- filter_duplicates(las1)
sensor <- track_sensor(las1, Roussel2020(pmin = 50))
las_norm <- normalize_intensity(las1, range_correction(sensor, Rs = 2000))
#> 3 coordinates detected in the sensor positions, parameter 'elevation' is not considered.
#> Error: 'gpstime range from the sensor does not contain gpstime range from the point-cloud
Any help is greatly appreciated!
