| 摘 要： | 通过对铀矿项目地质成果数据中的空间数据进行分析,把数量庞大的数据分为单点空间数据和图形空间数据两类。在EXCEL软件平台下,使用VBA编写空间数据平面四参数程序,实现四参数模型计算和所有单点坐标的2000国家坐标批量转换。又由于90%的铀矿地质成果图采用MapGIS格式,故采用EXCEL结合VBA在MapGIS二次开发平台上编写程序,实现对MapGIS格式图件的2000国家坐标系的批量转换。选择鄂尔多斯市巴音青格利铀矿地质普查项目进行空间数据2000国家大地坐标的转换,并对结果进行精度分析。结果表明:此方法在生产中精度可靠且容易操作,可以快速准确地完成铀矿地质资料空间数据的2000国家坐标系转换,值得在其他铀矿勘查地区推广。

| Abstract: | By analyzing the spatial attribute of a large amount of uranium geology achievement data,the data were divided into single point data and graphics data.Based on EXCEL software platform,a four-parameter program of spatial data plane was developed in VBA,which can realize the four-parameter model calculation and batch conversion of 2000 China coordinates for all single point coordinates.Since 90 percent of uranium geological maps are in MapGIS format,therefore,EXCEL and VBA were used to made a programs on MapGIS secondary development platform to realize batch conversion of 2000 China coordinate system.A geological project in Bayingqingli uranium deposit in Ordos Basin was selected for the conversion of spatial data 2000 China geodetic coordinates.The accuracy of the results was analyzed and the results showed that this method is reliable and easy to operate in production,it can quickly and accurately complete the 2000 China coordinate system conversion of uranium geological data. |
