Parameter description

Parameters
-i,--input
Type: Path
Remarks: mandatory, default: all vector data files in the current directory

Specifies the directory where the final results are stored.
If not specified, the results are created in the current working directory.

-k,--mask
Type: integer/boolean (0|1)
Default: 1 (True)
Remarks: optional
Description: create grid masks
If true (1), additional grid masks marking smooth/rough terrain are calculated.
