It addresses the need to store, manageand 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 combinationwith another spatial data type.Implementations of this part of ISO/IEC 13249 may exist in environments that also support geographicinformation, decision support, data mining and data warehousing systems.Application areas addressed by implementations of this part of ISO/IEC 13249 include, but are notrestricted to, automated mapping, desktop mapping, facilities management, geoengineering, graphics,location based services, multimedia and resource management applications.【中国标准分类号】: L74【国际标准分类号】: 35_060【页数】: 608P.;A4【正文语种】: 英语
