A method and system for storing and retrieving spatial data objects from a spatial database is discussed. The system stores multi-dimensional objects within the database by determining their position in a multi-tiered coordinate system. Once each object has been assigned to a particular coordinate, the object is further assigned to one of many overlapping sections within the coordinate system. Each object is assigned to a particular section of the coordinate system depending on its overall size and position. |
