It is unsuitable to directly adopt indirect polynomial correction method in the process from raw data to longitude latitude projection image.
并在大量实验的基础上指出，从原始数据图像到等经纬度投影图的纠正过程中不宜采用间接的多项式拟合法。
2
A convergence correction accommodates the change from rectangular coordinates to latitude and longitude.
收敛校正可使直角坐标系能适应经纬度(坐标)的变化。
3
The mathematics model is closely studied of residual correction of the dynamic fixed average position and static fixed position of longitude and latitude of the RBN/DGPS customer.
