| Abstract: | With the rapid development of collected spatial data technology,the spatial data which the human has increased sharply.Unfortunately,the magnanimous data is too excessive to be assimilated.How to effectively use and share the collected data is an important problem which is more urgent to resolve.Metadata system in spatial data warehouse provides a good method to resolve the problem.Therefore,this paper studies the technology of metadata in spatial data warehouse.Firstly,it discusses the concept and function of metadata in spatial data warehouse and the components of metadata system in spatial data warehouse.Secondly,it chiefly explores how to design the metadata system in spatial data warehouse,which concludes defining the standard of the metadata in spatial data warehouse,designing the structure and function of the system and the database of metadata. |
