 -ncc, --no-clip-city          Avoid clipping the point cloud data to the city boundary.
 -cf, --clip-file <file>       Provide a file path for a clipping boundary file to clip
                               the point cloud data to a specified area.
 -e, --epsg <epsg>             Set the EPSG code for user's clip file.
 -b, --bbox <bbox>             Specify a bounding box to clip the point cloud data. It should be comma-separated list with minx,miny,maxx,maxy
                               centered on the city polygon.

Download Point Cloud Data for Delft with All Classification Classes:

ahn_cli -c delft -o ./delft.laz

To Include or Exclude Specific Classes:

ahn_cli -c delft -o ./delft.laz -i 1,2

For Non-Clipped, Rectangular-Shaped Data:

ahn_cli -c delft -o ./delft.laz -i 1,2 -ncc

To Decimate City-Scale Point Cloud Data:

ahn_cli -c delft -o ./delft.laz -i 1,2 -d 2

Specify a Bounding box for clipping:

If you specify a b, it will clip the point cloud data with specified bounding box.

ahn_cli -o ./delft.laz -i 1,2 -b 194198.0,443461.0,194863.0,443694.0
