摘要
为进一步提升土地面积测量的精度,本次开展基于全球导航卫星系统(GNSS)技术的农村土地面积测量精度估算方法的研究。首先基于GNSS技术构建几何定位模型,对定位点中各参数进行深层解析;然后将得到的定位数据与测绘数据通过坐标系转换、栅格滑动赋值等步骤实现数据的归一化;最后将数据代入模型之中,完成测绘精度估算方法的设计。实验结果表明:在不同比例尺下,设计的估算方法预测的控制点与实际情况较相符,可进行准确的土地面积测量精度估算,具有一定可靠性。
In order to further improve the accuracy of land area measurement,this research was carried out on the accuracy estimation method of rural land area measurement based on global navigation satellite system(GNSS)technology.Firstly,the geometric positioning model was built based on GNSS technology,and the parameters in the positioning points were deeply analyzed;Then,the obtained positioning data and surveying data were normalized through coordinate system conversion,grid sliding assignment and other steps;Finally,the data was substituted into the model to complete the design of surveying and mapping accuracy estimation method.The experimental results showed that:under different scales,the control points predicted by the designed estimation method were more consistent with the actual situation,and couldaccurately estimate the accuracy of land area measurement,with certain reliability.
