摘　　要：针对地理信息系统(GIS)面数据批量更新缺乏技术方法问题,利用坐标参考不统一的点位坐标数据及存在多边形重叠的面数据,研究坐标参考转换、叠置分析及多边形创建原理,采用数据库技术、GIS二次开发及叠加分析算法改进相结合的方法,研究并实现了GIS面数据的批量更新技术方法。应用该技术更新矿产调查数据,更新结果表明,该方法可以高效完成矿产调查数据的批量更新;为GIS面数据更新提供一种技术方法。The following problems is solved ： using point coordinate data of different coordinate reference system and attribute data to update exploitation right, exploration right and mineral resources data of mineral investigation, and using those data of overlapping elements above to update overlapping exploitation right and overlapping explora- tion right data. The coordinate reference system of point coordinate data is unified, which had read from database, to 80 geographic coordinate. And then, those unified data is used to update exploitation right, exploration right and orefield data and added attribute information, based on the principle of surface of GIS data update. According to the principle of GIS analysis u imposed. The updated results pdated overlapping exploitation right and overlapping exploration right data are super- show that the method can be used for batch update mineral survey data.
