4. Create Vegetative Cover Factor Raster
Description
The vegetative cover management factor is a ratio comparing the soil loss from a specific type of vegetation cover. Vegetative cover raster is obtained by estimating relationship via landuse.
Usage
Parameters
| Direction | Type | Parameter Name | Data Type | Dialog Reference |
|---|---|---|---|---|
| Input | Required | Input DEM | Raster Layer | Input elevation raster. |
| Input | Required | Input Landcover Raster | Raster Layer | Input raster displaying landcover. |
| Input | Required | Input Landcover Lookup Table | Table View | This table must contain the fields Landcover and CFactor. Recall that C is a parameter in the RUSLE equation that defines the landcover management factor. The Landcover field will be used to find the associated value in the input raster. The tool will delete the field CFactor in the input Landcover if it already exists and readd and populate the field using the values from the lookup table. |
| Output | Required | Output Vegetative Cover Raster | Raster Layer | Output raster that will be used later in the toolset workflow as part of RUSLE equation to calculate erosion. |
