| Abstract: | In this paper, complex list is defined and the principle and method of memory management map vector data by using complex list are presented also. These have successfully settled the problem of the attribute and graphics data of map in memory management and memory linkage, improved the speed of data management greatly, and provided a good method of data management for all sorts of the system of geographic information and cartographic database in design. |
