geos.GEOSMakeValid ⇒ number ⏏
Returns a geometry which is valid according to the GEOS validity rules, and preserves as much as possible of the input geometry's extent, dimension, and structure.
The returned geometry may be a copy of the input, or a new geometry with different structure.
The returned geometry will be valid, or null if an exception occurs.
Kind: Exported member
Returns: number - a pointer to a valid Geometry, or null on exception
