基于GPS技术的测绘工程三维大地控制网的建设研究

Research on the construction of 3D geodetic control network based on GPS Technology

伴随我国基础建设的深入发展,对建筑楼宇的尺寸标准日益严苛,很大程度加强了测绘工作的难度。传统测绘工作通常采取人工测量,对于误差的控制则需通过反复测量、加权计算来克服,从而得出比较精准的测量值。然而这种方式操作复杂繁琐,精准度难以达到标准要求,而基于GPS技术的测绘工程三维大地控制网概念的出现,有效解决了上述问题和局限性。因此,本文基于GPS技术应用于三维大地控制网建设的依据,初步研究了基于GPS技术的测绘工程三维大地控制网的建设,并提出一系列建设建议,以期提高测绘工作效率和质量,推动我国建筑业的发展。

Along with the further development of our country＇s infrastructure construction, the standard of building size is becoming more and more severe, and the difficulty of Surveying and mapping is greatly strengthened. Traditional surveying and mapping work usually take artificial measurement, the error of the control needs to be repeated measurement,weight calculation to overcome, so as to get a more accurate measurement. However, in this way, the operation is complex and complicated, and the precision is difficult to meet the requirements of the standard, and the concept of three-dimensional geodetic control network based on GPS technology has effectively solved the problems and limitations. Therefore, this paper is based on the 3D geodetic control network construction based on the application of GPS technology,a preliminary study of the GPS technology in the construction of Surveying and Mapping Engineering Based on 3D geodetic control network, and put forward a series of suggestions to guide the construction, in order to improve the efficiency and quality of the surveying and mapping work, promote the development of China＇s construction industry.
