摘要
随着科学技术的发展,我国各地陆续建立了连续运行卫星定位地面站系统(CORS)。在我国国土资源信息化的快速普及的背景下,常规的全站仪导线控制测量或GPS静态定位测量,已不能满足城镇地籍控制测的需求。该研究结合内蒙古某城区的地籍测量工作实践,介绍了网络RTK技术在城镇地籍控制测量中的应用,并对网络RTK技术获取的城镇地籍控制测量数据与全站仪导线测量获得的测量数据进行精度比较和分析。结果表明,网络PTK技术克服了单基站作业半径的限制问题,不受天气、通视、地形的影响,工作效率高,精度能达到要求,可以代替全站仪导线测量用于城镇地籍控制测量。

AbstractAccording to the development of science technology, the whole country has built up CORS in succession. In the backdrop of national territory resources has quick popularized, the conventional total station or GPS couldnt satisfy the requirement of the cities and towns that cadastre control survey. This novel unites the control survey work of Inner Mongolia, introduce the use of RTK in the cities and towns that cadastre control survey and aim at the technology of RTK, compare the cities and towns that cadastre control survey with the traverse survey of total station about precision and analyze them. The results showed that network PTK technology can overcome limits of single base station operating radius with high efficiency and accurate, and not affected by weather, communication and terrain, which can take the replace of conventional total station and be used in cities and towns cadastre control measurement.
Key words Network RTK; CORS; The cadastre of cities and towns; Control measurement

城镇地籍测量工作是城镇地籍管理和城镇信息系统建设的基础,城镇地籍控制测量是根据控制点、界址点、地籍图的精度和基准要求,视测区范围的大小、测区内外现存国家控制点数量和等级等情况,按测量的基本原则和精度要求进行技术设计、选点、埋石、野外观测、数据处理等测量作业[1]。近年来,随着科学技术的飞速发展和我国国土资源信息化的快速普及,常规的地籍控制测量方法(如全站仪导线控制测量、GPS静态定位测量)已不能满足人们的需求。尤其是在城镇地籍测量中,由于通视性差、费时费力等原因,导致地籍控制测量作业效率低下、误差累积严重等问题。……
