Description

Creates a DEM grid with external and/or internal walls burnt in, except at the location of the breachlines.

Usage

Parameters

Parameter Name	Data Type	Direction	Type	Dialog Reference
Input DEM Raster	Raster Layer	Input	Required	Input dem onto which the walls will be built.
Inner Wall Height (DEM Z-Unit)	Double	Input	Required	Height added to the input dem at the location of the inner walls to build in these walls. The height of the external wall is twice this height.
Inner Wall Buffer (Number of Cells)	Long	Input	Required	Buffer in number of cells used when building the inner walls. Default to 0 – no buffering - i.e the walls will be one cell wide.
Breach Line Buffer (Number of Cells)	Long	Input	Required	Buffer in number of cells used when building the breach lines. Default to 0 – no buffering - i.e. the breaches will be one cell wide.
Output Walled DEM Raster	Raster Layer	Output	Required	Output dem with walls built in.
Input External Wall Polygon Feature Class	Feature Layer	Input	Optional	Optional. Polygon feature class defining the locations where the external walls will be built.
Input Internal Wall Feature Class	Feature Layer	Input	Optional	Optional. Polygon, point or line feature class defining the locations where the internal walls will be built onto the input dem.
Input Breach Line Raster	Raster Layer	Input	Optional
