ExtractSpecifiedIsoline
Instructions
Extracting specified contour lines can extract a certain number of specific value contour lines according to the user's needs. A series of feature values can be automatically generated based on the set range and interval, and the extracted raster dataset (RasterRDD) can be generated.
Parameter Specification
| Parameter Name | Default Value | Parameter Definition | Parameter Type |
|---|---|---|---|
| RasterRDD to be analyzed | RasterRDD that needs to be reclassified | RasterRDD | |
| Starting value | 0.0 | The initial starting value for generating contour lines | Double |
| Termination value | 0.0 | The maximum value of the generated contour line | Double |
| Isodistance | 0.0 | The interval value between two contour lines, which, together with the reference value, determines which contour lines to extract | Double |
| Field Name for Saving Elevation Values (Optional) |
zValue | The field name used to save the elevation values generated by contour lines. Users can name it themselves, and the default is zValue | String |
