cimg2Raster: Cimg to SpatRaster conversion

In lidaRtRee: Forest Analysis with Airborne Laser Scanning (LiDAR) Data

Cimg to SpatRaster conversion

Description

converts a cimg object to a SpatRaster object

Usage

cimg2Raster(cimg, r = NULL)

Arguments

cimg	raster object. raster of canopy height model, preferably filtered to avoid effect of holes on volume and surface computation
r	SpatRaster object. defines the extent and projection of conversion result

Value

A SpatRaster object

See Also

raster2Cimg

Examples

data(chm_chablais3)
chm_chablais3 <- terra::rast(chm_chablais3)

# convert raster to cimg object
chm_cim <- raster2Cimg(chm_chablais3)

# apply filtering
chm_cim_filt <- dem_filtering(chm_cim,
  nl_filter = "Closing",
  nl_size = 3,
  sigma = 0
)$non_linear_image

# convert to SpatRaster
chm_filt <- cimg2Raster(chm_cim_filt, chm_chablais3)

# plot SpatRaster
terra::plot(chm_chablais3)

# plot cimg object
plot(chm_cim)

# plot filtered cimg object
plot(chm_cim_filt)

# plot filtered SpatRaster
terra::plot(chm_filt)
