Manipulating geometry Instances

The geometry data type provides numerous built-in methods you can use to create new geometry instances based on existing instances.

To create a buffer around a geometry

STBuffer (geometry Data Type)

BufferWithTolerance

To create a simplified version of a geometry

Reduce

To create the convex hull of a geometry

STConvexHull

To create a geometry from the intersection of two geometries

STIntersection

To create a geometry from the union of two geometries

STUnion

To create a geometry from the points where one geometry does not overlap another

STDifference

To create a geometry from the points where two geometries do not overlap

STSymDifference

To create an arbitrary Point instance that lies on an existing geometry

STPointOnSurface
