摘要
利用MAPGIS软件,结合地质测量的自身特点,在扫描仪、计算机、绘图仪等外部设备的配合下,研究地形地质图的矢量化、数字化和地质工程测量的内业处理方法,提高图件的精度。根据分层分色原则,组织实现专题图、平面图、剖面图的绘制。并利用图形属性生成数据库,实现了地形地质图件的数据采集、编制、绘图、修改、制图的一体化。
Based on MAPGIS software, combined with the characteristics of geological measurement, assisted with equipments as the scanner, computer, plotter, etc., discussion is made on the terrain and geologic map in vectorization, digitization and geological project measurement. According to layered and colored separation principle, it presents the drawing of thematic picture, plane figure, and section system. Thus database formed, has realized data-gathering , work-out , drawing, integration revising, and maps-making.
