-
The
bounds()
method returns the bounding rectangle (Geometry) of a given geometry, such as a MultiPolygon. -
It accepts optional arguments for
maxError
to control reprojection accuracy andproj
to specify the output projection (defaults to EPSG:4326). -
This method is useful for determining the geographic extent of a geometry, which can be used for visualization, analysis, or filtering.
Usage | Returns |
---|---|
MultiPolygon.bounds(maxError, proj) | Geometry |
Argument | Type | Details |
---|---|---|
this: geometry | Geometry | Return the bounding box 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. |
