RTK技术复位固定样地的精度分析
Accuracy Analysis of Reset Fixed Sample Plot by RTK Technology
摘要
Abstract
RTK technology in engineering survey can provide real-time and high-precision positio-ning information.Based on the annual forest resources monitoring,the method of eliminating the difference of coordinates between different systems was used to reset the fixed sample plots by using network RTK.According to the different number of corner positioning marks reset in sample areas,the error in corner coordinates,the closure error of the sample areas and the perimeter difference were analyzed to detect whether they met the requirements of the technical specification for the preci-sion of the sample area reset.The results were as follows:1)All the corner positioning marks of the sample plots were reset,and the maximum error of the coordinates was 1.34 meters;2)Some of the corner positioning marks of the sample plots were lost,and the maximum closure error and perimeter error of the sample plots after replacement were 0.49 meters and 0.93 meters,respectively.All the 40 sample plots reset in this study met the accuracy requirements of the technical regulations.关键词
