| 摘 要： | 航测数据的航线间距与采样点间距差异很大,生成等值线时需要进行空间插值.以云南省江川地区的航测数据为实验数据源,分别采用反距离权重插值(IDW)、规则样条函数插值(Regularized Spline)、张力样条函数(Tension Spline)插值和Kriging插值等4种插值方法,对航测数据进行分析与比较,从中选出...

| Abstract: | The route distance of aerial survey data is quite different from the sample points distance.When sample points generate contours,they need spatial interpolation.This paper took the aerial survey data of Jiangchuan of Yunnan Province as the experimental data source,and applied the Inverse Distance Weighted(IDW),Regularized Spline,Tension Spline,Kriging four interpolation methods respectively for analyzing and comparing aerial survey data to chose one of the optimal interpolation methods and its parameters,so... |
