Abstract:

In view of the problem of showing and browsing large data set of spatial data in the distributed parallel environment quickly, not only one kind of massive spatial pyramid model based on a hierarchical and special topic mechanism, but high access performance tile map service based on database storage scheme under the tiles pyramid model technology were proposed. The mechanism of tile data file management and database management under the storage performance and response process were comparatively analyzed. Moreover, sand and dust storm observation data for 59 years was taken as an example to validate that this method can not only effectively organize and manage massive spatial data to achieve efficient data interoperability, but also quickly respond to client requests in the multi\|user concurrent access.

Key words: tiles pyramid model technology, large data set of spatial data, database, distributed parallel environment
