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.
Usage
Returns
Rectangle.centroid(maxError, proj)
Geometry
Argument
Type
Details
this: geometry
Geometry
Calculates the centroid of this geometry.
maxError
ErrorMargin, default: null
The maximum amount of error tolerated when performing any necessary reprojection.
proj
Projection, default: null
If specified, the result will be in this projection. Otherwise it will be in EPSG:4326.

It accepts `maxError` to define the tolerated reprojection error and `proj` to specify the output projection; otherwise, it defaults to EPSG:4326. For example, applying `centroid` to a rectangle returns its center point. The method's result, which is a `Geometry` object, can be printed and displayed on a map, as shown in JavaScript and Python code examples.\n"]]
