| Abstract: | In the field of GIS,how to store,manage and fast display mass grid data has been studied as a main problem all the time. In this article, the author studies the index mechanism of muhi-scale mass grid data by creating quard-tree data structure, spatial index and adjoining relations based on grid spatial data as research object. |

| Keywords: | mass grid data multi-scale quard-tree data blocks |
