Parameters
| Name | Required | Default value | Comment |
|---|---|---|---|
| Source | + | Source grid layer. | |
| Destination | + | Destination vector layer. | |
| Field | (empty) | If not empty, the attribute field with the specified name will be populated with the elevation values of the contours. | |
| ContourBase | 0.0 | The “base” relative to which contour intervals are applied. | |
| ContourInterval | 100.0 | The elevation interval between generated contours. | |
| CustomNoData | False | If True, the NoDataValue will be used as NoData value. | |
| FixedLevels | The list of fixed contour levels at which contours should be generated, e.g. 0,100,200,300,400,500. | ||
| MinSize | 0.0 | Minimum dimension in meters for generated features; Minimum length for polylines, minimum area for polygons. | |
| Mode | Polylines | Type of contour generator output. One of following: Polylines, ClosedPolylines, OverlappingPolygons, Polygons. | |
| NoDataValue | -9999.0 | The value to use as a NoData value. | |
| Smoothen | False | If True, then the generated contours will be smoothened. | |
| SmoothFactor | 5 | Smooth factor. |
