opt_chunk_buffer(ctg)

opt_chunk_buffer(ctg) <- value

opt_chunk_size(ctg)

opt_chunk_size(ctg) <- value

opt_chunk_alignment(ctg)

opt_chunk_alignment(ctg) <- value

opt_progress(ctg)

opt_progress(ctg) <- value

opt_stop_early(ctg)

opt_stop_early(ctg) <- value

opt_wall_to_wall(ctg)

opt_wall_to_wall(ctg) <- value

opt_independent_files(ctg)

opt_independent_files(ctg) <- value

opt_output_files(ctg)

opt_output_files(ctg) <- value

opt_laz_compression(ctg)

opt_laz_compression(ctg) <- value

opt_merge(ctg)

opt_merge(ctg) <- value

opt_select(ctg)

opt_select(ctg) <- value

opt_filter(ctg)

opt_filter(ctg) <- value

Arguments

`ctg`	An object of class LAScatalog
`value`	An appropriate value depending on the expected input.

Examples

LASfile <- system.file("extdata", "Megaplot.laz", package="lidR")
ctg = readLAScatalog(LASfile)

plot(ctg, chunk_pattern = TRUE)

opt_chunk_size(ctg) <- 150
plot(ctg, chunk_pattern = TRUE)

opt_chunk_buffer(ctg) <- 10
plot(ctg, chunk_pattern = TRUE)

opt_chunk_alignment(ctg) <- c(270,250)
plot(ctg, chunk_pattern = TRUE)

summary(ctg)

opt_output_files(ctg) <- "/path/to/folder/templated_filename_{XBOTTOM}_{ID}"
summary(ctg)
