| 摘 要： | 随着测绘技术的不断发展,空间大地测量技术越来越受重视,其中GPS定位技术在测量各个领域得到了广泛的应用.原来的经典测量方法越来越受其空间性和时限性限制,而GPS测量技术正是突破了经典测量中的种种限制,达到全天候采集和不受空间通视条件等限制,作业效率大幅度提高,特别在城市控制测量中,由于建筑物密集等干扰因素,常规测量方法费时且精度有限,GPS更是得到充分应用.本文通过锦州GPS控制网的建立,系统阐述了GPS在城市控制测量应用中的整个过程.

| Abstract: | With the continuous development of surveying and mapping technique,space geodetic techniques is receiving more and more attention,among which GPS technique is applied widely in various surveying field.GPS technique breaks through the limits of traditional surveying methods caused by time and space via all-weather and all visibility condition data collection,greatly improves operation efficiency,and is applied widely especially in cities where conventional surveying is time consuming and of limited accuracy due to the interference caused by the density of buildings.Based on the establishment of Jinzhou GPS control network,this paper elaborates on the process of the applications of GPS technique in urban control surveying. |
