use lasR to combine DTM and normalize step — lasr_dtm

Combining DTM and normalize step using lasR functionality

Usage

lasr_dtm_norm(dtm_file_name, frac_for_tri = 1, dtm_res = 1, norm_accuracy = 2)

dtm_file_name: string. Where to write the DTM.
frac_for_tri: numeric. The fraction of points used in Delauny triangulation.
dtm_res: numeric. The desired resolution of the DTM produced in meters.
norm_accuracy: numeric. see chunk_las_catalog. Choose processing accuracy. accuracy_level = 1 uses DTM to height normalize the points accuracy_level = 2 uses triangulation with high point density (20 pts/m2) to height normalize the points accuracy_level = 3 uses triangulation with very high point density (100 pts/m2) to height normalize the points
