经济统计地理信息系统中的一种地图自动更新算法

An algorithm of map automatic updating for economic statistic GIS

地理信息系统作为一种先进的信息处理技术,已成功应用于诸如城市规划管理、土地资源管理和交通管理等工作,但在统计行业中的应用研究还比较薄弱,相关文献还比较少见.针对统计数据的特点和用户需求,设计实现了一种适用于经济统计地理信息系统的地图自动更新算法,并已将其应用于银川市二、三产业经济统计地理信息系统,解决了地图自动更新问题.应用证明该算法增加了电子地图的灵活性、动态性和可扩充性.

Being an advanced information processing technology,GIS has been very successful in applications such as city planning management,land resource management , traffic management etc. But it is less used in statistic trades. Considering the characteristics of the statistic data and the demands of the user,we propose an automatic updating algorithm for electronic map in economic statistic GIS. Experiments in the application of project show that the electronic map is flexible,dynamic and extendible.
