ee.Geometry.Polygon.toGeoJSONString

AI-generated Key Takeaways

The toGeoJSONString() method returns a GeoJSON string representation of a geometry.
This method can be applied to a Polygon object to get its GeoJSON string.
The examples demonstrate its use in both JavaScript and Python.

Returns a GeoJSON string representation of the geometry.

Usage	Returns
`Polygon. toGeoJSONString ()`	String

Argument	Type	Details
this: `geometry`	Geometry	The Geometry instance.
