| Abstract: | Aiming at the management and quickly displaying of the massive remote sensing images,this paper summarized the organization and management methods of pyramid data based on RDBMS.Also it introduced the tile and hierarchy data structure and quickly indexing technique in detail,and from building,indexing,scheduling and cache four aspects comparatively discussed and compared the two pyramid building strategies for multi-source image database.Finally,it developed a system based on the specific projects,verified the comparison results,and gave the principle of selection. |
