基于MapGIS组件技术实现化探异常参数的计算

摘要

Based on the visual basic system, a programme was developed to calculate the geochemi-cal anomaly parameters. First, a points workspace including the geochemical element analysis data was created with the MapGIS COM technology in the programme, then the MapGIS geochemical anomaly region file(. Wp) was input, Finally, calculated the parameters using the intersection analysis of point file data and region file data. The results can be output to Excel file easi-ly.%在Visual Basic环境中编写一个求化探异常参数的程序,程序首先运用MapGIS组件(COM)技术,构造了含有元素分析数据的点工作区,然后读入MapGIS异常区文件(.wp).通过点对区的相交分析,提取出异常数据,进而对数据进行计算,求得异常参数.程序结果输出到EXCEL工作表中,非常实用.
