Returns the convex hull of the given 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.
Calculates the convex hull of this geometry.
|ErrorMargin, default: null|
The maximum amount of error tolerated when performing any necessary reprojection.
|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.
