Compute Convex Hull
Feature Description
Computes the convex hull for a geospatial feature dataset, resulting in a convex hull polygon feature object (FeatureRDD) for the dataset.
Common application scenarios include calculating the convex hull for a class of elements to obtain their overall distribution area, used to compare distribution locations and analyze surrounding influencing factors. For example, by computing the convex hull for signal cold spots in a building area, one can statistically analyze areas with weak signals.
Parameter Description
| Parameter Name | Default Value | Parameter Interpretation | Parameter Type |
|---|---|---|---|
| Input Feature Dataset | The input feature dataset | FeatureRDD | |
| Group Field | Sets the group field, where geometries with the same field value will construct one convex hull. If the group field is empty, all geometries are used to construct a single convex hull. | String |
