BBox Operators
Reported by nofxx | November 30th, 2008 @ 05:33 AM | in Call me a plugin
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?
