geos.GEOSisValid ⇒ number ⏏
Tests whether a geometry is valid according to the OGC rules for geometry validity.
Kind: Exported member
Returns: number - 1 if the geometry is valid, 0 if it is invalid, or -1 if an error occurred.

| Param | Type | Description |
|---|---|---|
| geom | number | The geometry to test. |
geos.GEOSisValidDetail ⇒ number ⏏
Returns a valid_detail row, containing a boolean stating if a geometry is valid, a varchar stating a reason why it is invalid and a geometry pointing out where it is invalid.
Kind: Exported member
Returns: number - 1 if the geometry is valid, 0 if it is invalid, or -1 on error
See: GEOSisValidDetail
