NAME

       pklas2img - Rasterize LAS/LAZ point clouds with filtering/compositing options

SYNOPSIS

       pklas2img -i lasfile -o output [options] [advanced options]

DESCRIPTION

       pklas2img   converts   a   las/laz  point  cloud  into  a  gridded  raster  dataset.   The
       implementation is based on  liblas  ⟨http://www.liblas.org/⟩  API.   You  can  define  the
       bounding  box,  grid cell size and spatial reference set.  The composite rule for multiple
       returns within a single grid cell can be set with the option -comp.  The default attribute
       is  z  (height), but can also be intensity (if available), the scan angle rank (-n angle),
       the return number (-n return) or the total  number  of  returns  in  that  grid  cell  (-n
       nreturn).   To  select  specific  returns  only, set the option -fir (first, last, single,
       multiple, or all).

              (low vegetation), 4 (medium vegetation), 5 (high vegetation), 6 (building), 7  (low
              point,  noise),  8  (model  key-point), 9 (water), 10 (reserved), 11 (reserved), 12
