Returns a feature containing the point at the center of the highest-dimension components of the geometry of a feature. 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 | Feature.centroid(maxError, proj) | Feature |
| Argument | Type | Details | this: feature | Element | Calculates the centroid of this feature's default 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 WGS84. |
