Author: O. Conrad (c) 2001
Specification: grid
Menu: Terrain Analysis|Preprocessing

Parameters

	Name	Type	Identifier	Description	Constraints
Input	DEM	Grid (input)	`DEM`	Digital Elevation Model that has to be processed	-
Input	Sink Route (*)	Grid (optional input)	`SINKROUTE`	-	-
Output	Preprocessed DEM (*)	Grid (optional output)	`DEM_PREPROC`	Preprocessed DEM. If this is not set changes will be stored in the original DEM grid.	-
Options	Method	Choice	`METHOD`	-	Available Choices: [0] Deepen Drainage Routes [1] Fill Sinks Default: 1
	Threshold	Boolean	`THRESHOLD`	-	Default: 0
	Threshold Height	Floating point	`THRSHEIGHT`	The parameter describes the maximum depth of a sink to be considered for removal [map units]. This allows to exclude deeper sinks from filling.	Default: 100.000000
(*) optional
