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 |
