- Spatial functions for distance, area, and length
- Spatial function for buffering (new to Locator in release 11g)
- Open, standard SQL access to spatial operations
- Whole Earth geometry model that provides comprehensive storage, management and use of geodetic data
- Function-based spatial indexes
- Long transactions (through Oracle Workspace Manager feature)
- Coordinate system support based on the European Petroleum Survey Group (EPSG) data model
- Explicit coordinate transformations
- Support for SQL/MM Spatial types and operators** (new to Locator in release 11g)
