Abstract
The next type of indexing we need to look at is spatial indexing, which relates to the spatial data types. Introduced in SQL Server 2008, spatial data types advance the storage capabilities of SQL Server allowing data that defines shape and location information. Before these enhancements, spatial data was often stored as string or numeric values without meaning within the database and required cumbersome conversions and calculations to resolve the information into something meaningful.
