The spatiotemporal characteristics of statistical data were research challenges in Statistical GIS.This paper mainly studies an effective method to implement organization and query of spatiotemporal statistical data.First,it introduces the research situation of spatiotemporal data model and analysis the spatiotemporal characteristics of statistical data.Then it proposes a data model using object-oriented method and introduces how to realize it in the database.At last,some of the most common query algorithms in the Statistical GIS are introduced.Proved by programming realization,long-term statistical data can be effectively organized and stored in the database,spatiotemporal snapshot query and sequences query can be well executed in this way.
