How it maps to the operation
| Operation parameter | Parameter here | Note |
|---|---|---|
raster | elevation | Not stated |
output | slope | Not stated |
units | format | degrees = degrees; percent = percent |
z_unit | Not stated | always crs-units. Elevation is taken in the project's horizontal units; otherwise set zscale. |
Differences from the operation
- The same module writes aspect (and curvatures) when those outputs are named; its aspect convention differs from compass bearings unless -n is set.
