Geospatial Types

Geospatial types contain information about points, paths, and polygons on the surface of the Earth. For more information, see Working with Geospatial Features.

Data Type


Size (Not Null)

8 bytes


See note


The space consumed by the path and polygon data in Geography columns is dependent on the complexity of the objects. Very roughly, a Geography value consumes 24 bytes per vertex, plus a 64 byte overhead, plus some minor overhead for each “ring” in a multipolygon.

Indexing a Geography object may also consume more space than indexes over other datatypes. The rule of thumb is 40 bytes * the value of the RESOLUTION parameter of the index, per row.
