烟台开发区高精度工程控制网的建立

ESTABLISHMENT OF ENGINEERING CONTROLLING NETWORK WITH HIGH PRECISION IN YANTAI CITY DEVELOPING ZONE

表述了为提高平面精度和高程拟合精度采用的数据处理方法和达到的精度指标,提出了对平面网起算点进行内符精度检测,采用多种高程拟合方案对已知GPS水准点进行精度检验,综合考虑内符合和外符合精度,实现最优高程拟合的观点。

The paper pointes out that, with checking the conforming precision of standard points data inside plane network, when elevation simulating and conforming is carried out, precision checking for known GPS level point data would be finished in several simulating and conforming plans. The best way for simulating and conforming would be searched by not only considering conforming precision inside but also considering conforming precision outside.
