BBox Operators

#6

These operators utilize indexes. They compare bounding boxes of 2 geometries


  A &< B (A overlaps or is to the left of B)
  A &> B (A overlaps or is to the right of B)
  A << B (A is strictly to the left of B)
  A >> B (A is strictly to the right of B)
  A &<| B (A overlaps B or is below B)
  A |&> B (A overlaps or is above B)
  A <<| B (A strictly below B)
  A |>> B (A strictly above B)
  A = B (A bbox same as B bbox)
  A @ B (A completely contained by B)
  A ~ B (A completely contains B)
  A && B (A and B bboxes interact)
  A ~= B - true if A and B geometries are binary equal?
