Calc Slope Map
Description
This functor calculates a slope map based on a height map.
Inputs
| Name | Type | Description |
|---|---|---|
| Elevation | Map | A height map. The height is assumed to be in meters. It may have null values. |
Optional Inputs
| Name | Type | Description | Default Value |
|---|---|---|---|
| use Diagonals Are Longer | Bool | Indicates if the distance between the cells at the diagonals must be increased by the factor of 1.414213562. | True |
| Slope In percent | Bool | If true, the slope will be calculated in percent; otherwise, it is calculated in degrees. | False |
| Cell Type | Cell Type | The slope data cell type. | Signed 32 Bit Integer |
| Null Value | Int | Null value of the slope map. The cell type must be appropriate. | -2147483648 |
| Slope Is Sparse | Bool | If true, set the output map as sparse. | False |
Output
| Name | Type | Description |
|---|---|---|
| Slope | Map | The slope map. Map format has the same dimensions of the source map. |
Group
Notes
The functor calculates the slope of a cell using the height difference for each neighbor cell and its dimension. The largest slope is chosen as the output value.
