基于二次曲面半参数模型的 GPS高程拟合及应用研究

摘要

Semi-parametric regression model is being used in the field of surveying and mapping data processing , this paper put a combination method of the semi -parametric adjustment model and quadric fitting , using data to prove this method effective and afford other method to solve height problem in topographic map production .%半参数回归模型在测绘数据处理领域中被广泛应用，本文采用把半参数回归模型与传统的二次曲面拟合相结合的方法，对测量数据进行二次曲面拟合和高程的推估与内插，对传统地形图测绘的高程问题提供一种解决途径。
