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.
