Design and Realization of a New Method for Increasing the Querying and Statistical Speed of Vector Map

SONG Guo-min,JIA Fen-li  
Query and count are the basic functions of GIS.The key of these functions is building the index of map data.This paper introduced a new method with eata partition.The result of experiment showed that this method can increase the speed of querying and counting,save of the memory of conputer system.
