ISO/IEC 13249-3:2003

ISO/IEC 13249-3:2003:

• introduces the Spatial part of ISO/IEC 13249 (all parts);
• gives the references necessary for ISO/IEC 13249-3:2003;
• defines notations and conventions specific to ISO/IEC 13249-3:2003;
• defines concepts specific to ISO/IEC 13249-3:2003;
• defines spatial user-defined types and their associated routines.

The spatial user-defined types defined in ISO/IEC 13249-3:2003 adhere to the following.

• A spatial user-defined type is generic to spatial data handling. It addresses the need to store, manage and retrieve information based on aspects of spatial data such as geometry, location and topology.
• A spatial user-defined type does not redefine the database language SQL directly or in combination with another spatial data type.

Implementations of ISO/IEC 13249-3:2003 may exist in environments that also support geographic information, decision support, data mining and data warehousing systems.

Application areas addressed by implementations of ISO/IEC 13249-3:2003 include, but are not restricted to, automated mapping, desktop mapping, facilities management, geoengineering, graphics, multimedia and resource management applications.
