由野外实测数据直接生成MAPGIS地质基础图件方法

传统纸介质手工制图存在信息实时再现滞后、共享交换不便等弊端,即便目前普遍使用计算机制图,也只是对纸介质底图进行二次描绘,不是真正意义上的计算机数字化制图和专业应用.因此,由野外实测数据直接进机处理生成地质基础图件,已成为专业人员在实际工作中急需解决的实际问题.笔者尝试以中国地质大学开发的MAPGIS6.6为主,辅以常用图表处理软件等,将原始数据转换成MAPGIS明码格式文件,导入成图系统,经系统处理直接成图,基本解决了野外实测数据直接进机处理生成地质基础图件的问题,其成图精度高,基本图形、数据共享,成果信息实时再现,能够进行基本的空间分析,可实现信息全息化,成图质量可通过源数据检查等.

TRANSFERRING FIELD MEASUREMENTS TO MAPGIS GEOLOGICAL MAPS

Traditional hand drawn maps on paper were use primary data that is difficult to update exchange and share.Even currently widely used computer mapping is not being used professionally,as it is mostly copied directly from the paper maps.Therefore,in the application of computerized digital mapping by transferring field measurements and other data to basic geological maps is an immediate challenge faced by geologists.The authors used MAPGIS 6.6,developed by China University of Geology,with other commonly used table/map processing software,and transferred primary field data into MAPGIS format for input into map a processing system.This procedure produced final geological maps directly from the input of primary field data to the computer.The method is simple and practical and the final map is highly accurate.In addition all data can be shared,exchanged,and updated easily.The final output can also be used for 3D analysis as it is fully digital.All final maps can be examined through the primary data.
