GPS与Excel、Mapgis相结合在化探工作中的应用

The application of combining GPS with Excel and Mapgis in the drawing in geochemical exploration working

本文通过论述利用Excel强大的数据分析及转换功能,转换手持式GPS坐标数据;利用Mapgis地理分析系统中空间分析模型子系统及投影变换模型子系统,实现化探次生晕测点自动标注、化探异常图的自动圈定,减轻了地质人员的劳动强度,提高工作效率和质量。

Through the use of Excel with powerful data analysis and conversion functions, conversion portable GPS coordinates data; Mapgis geographic analysis system, using spatial analysis and projection models subsystem and model subsystems used to achieve the automatic labelling of the secondary halo measuring points and automatic delineation of the anomalous maps in geochemical exploration working, reducing geologic staff＇ labor intensity and raising labor productivity and quality.
