半参数模型在地形图测绘中的应用

Application of Semi-parametric Regression Model in Topographic Map Surveying

半参数回归模型在测绘数据处理领域中被广泛应用。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,为传统地形图测绘的高程采集问题提供了一种解决途径。

Semi-parametric regression model is being used in the field of surveying and mapping data processing. This paper put a combination method for the semi-parametric adjustment model and quadric fitting, and used data to prove this method effective and afford other method to solve height problem in topographic map production.
