摘要
针对如何削弱大区域GPS水准拟合模型中的模型误差问题,提出了带有模型误差改正的建模方法,并将该模型应用于长沙地区的GPS水准拟合,结果表明,该模型的精度较高,解决了长沙地区工程项目中GPS高程转换问题。
On how to reduce the model error of large region GPS leveling interpolation model, the modeling with model error correction was given and applied to the GPS leveling interpolation of Changsha region. The results showed that the accuracy of the model was more higher to resolve GPS height transformation of Changsha projects and hayed great practical value.
