摘要
通过分析青龙寺井田宜采用的测量坐标系,求出了适合本测区测量边长归化投影变形的数学模型,计算出了在井田范围内将实测边长归化投影到国家统一坐标系下的改算数,在此基础上提出了边长归化投影的分区乘系数改算优化方法,并结合实例验证了该方法在精度和应用方面都优于建立矿区独立坐标系法。
Through the analysis of the QingLongSi field appropriate measurement coordinate system, the paper establishes the surveyed area for measuring length mathematical model of projective deformation domestication, calculates the scope will be measured in the field to the national unified projection coordinate to count, and based on this, advances the division by distance projection of naturalization to calculate coefficient of optimization method, combing with the method is verified by examples in precision and applications are superior to establish independent coordinate system.
