Flags:

-m

Use 3D raster mask (if exists) with input map

-r

Use the same resolution as the input 3D raster map for the 2D output maps, independent of the current region settings

--overwrite

Allow output files to overwrite existing files

--help

Print usage summary

--verbose

Verbose module output

--quiet

Quiet module output

--ui

Force launching GUI dialog

Parameters:

input=string [required]

3D raster map(s) to be converted to 2D raster slices

output=string [required]

Basename for resultant raster slice maps

type=string

Type of raster map to be created
Storage type for resultant raster map
Options: CELL, FCELL, DCELL
CELL: Integer
FCELL: Single precision floating point
DCELL: Double precision floating point

multiply=float

Value to multiply the raster values with
Coefficient a in the equation y = ax + b

add=float

Value to add to the raster values
Coefficient b in the equation y = ax + b

Map type conversions

Type of resulting 2D raster maps is determined by the type of the input 3D raster, i.e. 3D raster of type DCELL (double) will result in DCELL 2D rasters. A specific type for 2D rasters can be requested using the type option.

The type option is especially advantageous when the 3D raster map stores categories (which need to be stored as floating point numbers) and the 2D raster map should be also categorical, i.e. use integers. The type is set to CELL in this case.

Modifying the values

The values in the 3D raster map can be modified prior to storing in the 2D raster map. The values can be scaled using the option multiply and a constant value can be added using the option add. The new value is computed using the following equation:

y = ax + b

where x is the original value, a is the value of multiply option, b is the value of add option, and y is the new value. When multiply is not provided, the value of a is 1. When add is not provided, the value of b is 0.
