Determining Relationships Between geography Instances
The geography data type provides many built-in methods you can use to determine relationships between two geography instances.
To determine if two instances comprise the same point set
To determine if two instances are disjoint
STDisjoint (geometry Data Type)
To determine if two instances intersect
STIntersects (geometry Data Type)
To determine the point or points where two instances intersect
STIntersection (geography Data Type)
To determine the shortest distance between points in two geography instances
STDistance (geometry Data Type)
To determine the difference in points between two geography instances
STDifference (geography Data Type)
To derive the symmetric difference, or unique points, of one geography instance compared with another instance
