GPS技术在安徽怀远-蒙城一带金、铁多金属矿产调查中的应用

Application of GPS technology in survey of gold and iron polymetallic ore deposits around the Huaiyuan-Mengcheng area,Anhui Province

采用GPS定位技术建立各种类型和精度等级的测量控制网是GPS在测量中最早、最广泛的应用之一。相对于常规测量方法,GPS技术具有测量精度高、选点灵活、无须造标、布网成本低、观测时间短、处理自动化、作业效率高等显著优点。在动态测量中,GPS技术更是以无须通视、随测随走、快速出结果的优势被广泛应用。本文就GPS在物探测量中的案例应用,展开描述,探索其规律,总结优缺点,为今后物探测量提供有益借鉴。

One of the earliest and most extensive applications of GPS is to establish various types and accuracy levels of measurement control network.Compared with conventional survey methods,GPS technology is mature and has such advantages as high measurement accuracy,flexible point selection,no need for signal erection,low networking cost,short observation time,processing automation and high operation efficiency.In dynamic surveying,GPS technology is widely used because it has no requirement for sighting condition,the operator can go to another spot as soon as he finishes a survey at one spot,and the survey result is generated timely.This paper introduces a case of the application of GPS in geophysical survey,describes it in detail in an effort to find out the law and summarize the advantages and disadvantages,providing a reference for future geophysical survey.
