| Abstract: | Vector data is the important data source in large area virtual battle-field environment. The paper researches the storage of line vector data based on quad-tree architecture, solves the problems of line vector data dividing and sparse and recovers the cracks between different LOD(lever of detail).The method has been tested by large scale data. It can produce quad-tree based line vector data base rapidly and make real-time and seamless walk-through. |

| Keywords: | line vector data quad-tree sparse |
