一种用于网络地图的栅格索引技术
Grid Index Technology Applied in Web Map
摘要
Abstract
The R-tree method, which is a popular method used in spatial database, has limitations for Web map service. This paper proposes a grid index method utilizing Anti-Grain Geometry(AGG) as the engine for the map between geographic feature and image pixel. After illustrating the design and implementation of this method, it conducts experiments to compare the performance of R-tree and the proposed method. The result shows the significant performance advantage about 22% of the new method.关键词
