ST_Disjoint

ST_Disjoint takes two geometry columns and returns a boolean column. The function returns True if the first and second geometry are disjoint; otherwise, it returns False. Two geometries are disjoint if they are not overlapping, touching, or intersecting each other.

If the two geometry columns are in different spatial references, the function will automatically transform the second geometry into the spatial reference of the first.

Function	Syntax
Python	`disjoint(geometry1, geometry2)`
SQL	`ST_Disjoint(geometry1, geometry2)`
