AI-generated Key Takeaways
-
The
bounds()method returns the bounding rectangle of a geometry. -
It can accept optional
maxErrorandprojarguments to control reprojection and output projection. -
The method is demonstrated with JavaScript and Python examples using a
MultiLineStringgeometry.
| Usage | Returns |

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. |
