WebbPolygons can intersect in three ways: Overlap—Area of overlap can be produced by leaving the Output Type to its default value (LOWEST). Common boundary/touch at a line—This type of intersection can be produced by specifying LINE as the Output Type. Touch at a point—This type of intersection can be produced by specifying POINT as the Output Type. green counseling \u0026 associates
