How it maps to the operation
| Operation parameter | Parameter here | Note |
|---|---|---|
raster | elevation | Not stated |
output | aspect | Not stated |
z_unit | Not stated | always crs-units. Elevation is taken in the project's horizontal units; otherwise set zscale. |
Differences from the operation
- Without the n flag, aspect is counterclockwise from east (east 0, north 90); this mapping sets it, for compass bearings (north 0, clockwise).
