Research On The Intergration Of The Diversity Geographic Data Sources On The Internet

With the development of Internet,distributed system structure has becomed developmental direction of GIS depend on Web. The much more geography data put on extensity separate computer, at the same time, the share question of geography data is appeared too, the share mechanism of geography data is among of keys that make "numeric earth" operate .the developmet of Internet and database technology and WebGIS,that offer new thinking and resolvent to the share of geography data.The text encircle the masterstroke of diversity geographic data sources, discussed geographic data Intergration of the investigation actuality and develop trend; analyzed several kinds mode of geographic data Intergration,and base on that put forward questions that geographic data Intergration should resolve,because of limiting research time,the text research stressly the Intergration of different physics place geographic data, different storage format geographic data on Internet, analyzed particularly the diversity of much geographic data sources, exoatiated on the feasibility and require of geographic data Intergration,and any analyzed the strategy of geographic data Intergration,that is the theory base of geographic data Intergration; introduced the pivotal technology of geographic data Intergration for example the manage method of spatial data,the application of spatial metadata,the technology of Java and JDBC.that offer technology basis to geographic data Intergration.and discuss thoroughly the effect of spatial meta data on geographic data Intergration ,and the significance on network share,researched on meta data frame that can manage and get availably distributing geographic data.Base on that, Research on the method of the Diversity Geographic Data Sources IntergrationOn the Internet-distributing components based on metadata,and design the system structure of dataIntergration middle parts, introduced realization process of them.At last, reaserched on experimentation and analysis about the task, the experiment result indicate that the method is feasible,because of limiting time, the partial design and experiment would be perfect ulteriorly.
