PAGE MAPPING METHOD OF SPACE DATA |
摘要 |
PURPOSE: A page mapping method of space data is provided to perform spatial indexing in a spatial grid method according to spatial proximity to map the space data or re-map change data through a mapping table, thereby reducing the frequency of merging or erasing data pages. CONSTITUTION: According to spatial proximity, a spatial index is given to space data(504). The spatial index shows the spatial proximity. A logical page or a physical page is mapped according to the spatial proximity in a mapping table for the space data where the spatial indexing is performed(506). When the space data is changed, a changed page is remapped in a residual logical page or a residual block of the mapping table(508~512).
