   Hi, which methods do you want to use?

   I want to use functions for geofencing, PolygonUtils.isPointInPolygon2D()

   Will OperatorDisjoint work for you?
   Here is an example of how to use it.

   Point point = new Point(1, 1);
   Polygon polygon = new Polygon();
   polygon.startPath(0, 0);
   polygon.lineTo(0, 3);
   polygon.lineTo(3, 3);
   polygon.lineTo(3, 0);
   
   SpatialReference spatialRef = SpatialReference.create(4326);
   
   // Returns false in this case meaning that the point is in the polygon
   boolean disjoint = OperatorDisjoint.local().execute(point, polygon, spatialRef, null);

   Yes, this works for me, thank you. but is it the best and fastest way? because i'm working on bigdata use case... will PolygonUtils be faster?

   @SiefSeif Use OperatorDisjoint. Avoid creating objects in a loop, you could also move OperatorDisjoint.local() call outside of the loop. The spatial reference is used to extract a tolerance value of about 1 mm and is used close to polygon borders, you can pass null spatial reference if you don't care about the tolerance.
