EnvelopeAggregate ( geography_operand )
geography_operand
Is a geography type table column that holds the set of geography objects on which to perform an envelope aggregate operation.
[!INCLUDEssNoVersion] return type: geography
A FullGlobe object is returned when the resulting bounding object is bigger than a hemisphere. This method is not precise.
Method returns null if the input has different SRIDs. See Spatial Reference Identifiers (SRIDs).

Method returns null if all inputted values are null.
The following example performs a EnvelopeAggregate on a set of geography location points within a city.

SELECT City,
geography::EnvelopeAggregate(SpatialLocation) AS SpatialLocation
FROM Person.Address
WHERE PostalCode LIKE('981%')
GROUP BY City;
