Geometry centroid

Supported in: Batch, Streaming

Return the centroid, or "center of mass", of the geometry using a spherical approximation of the globe. If the geometry is a collection of mixed dimensions, only the elements of the highest dimension will contribute to the centroid (e.g. in a collection of points, lines and polygons, points and lines are ignored).
