ee.Feature.convexHull
Returns the feature with the geometry replaced by the convex hull of the original geometry. The convex hull of a single point is the point itself, the convex hull of collinear points is a line, and the convex hull of everything else is a polygon. Note that a degenerate polygon with all vertices on the same line will result in a line segment.
| Usage | Returns |
|---|
Feature.convexHull(maxError, proj) | Feature |
| Argument | Type | Details |
|---|
this: feature | Element | The feature containing the geometry whole hull is being calculated. |
maxError | ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
proj | Projection, default: null | The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere. |
