Returns a point at the center of the highest-dimension components of the geometry. Lower-dimensional components are ignored, so the centroid of a geometry containing two polygons, three lines and a point is equivalent to the centroid of a geometry containing just the two polygons.

MultiPoint.centroid(maxError, proj)Geometry
this: geometryGeometry

Calculates the centroid of this geometry.

maxErrorErrorMargin, default: null

The maximum amount of error tolerated when performing any necessary reprojection.

projProjection, default: null

If specified, the result will be in this projection. Otherwise it will be in WGS84.
