How it maps to the operation
| Operation parameter | Parameter here | Note |
|---|---|---|
layer | input | Not stated |
output | output | Not stated |
field | zfield | Not stated |
resolution | Not stated | resolution (x and y) must come with extent (xmin, ymin, xmax, ymax); give the grid by both, or by size. |
power | power | Not stated |
Differences from the operation
- Uses every point by default; radius, max-points and min-points limit the search. Cells with too few points get nodata (default 0).
