SVR在平均海面高格网化中研究

Applicating SVR in the Gridding of Mean Sea Surface Height Data

研究了利用SVR进行平均海面高格网化的方法,并结合平均海面高数据的特点,确定了格网化半径;利用Surfer11软件中几种数据插值方法,对平均海面高进行了格网化处理,并对结果进行交叉验证;将SVR格网化方法所得平均海面高与surfer11格网化所得平均海面高进行了对比,结果表明利用SVR进行平均海面高格网化是切实可行的。

This paper shows the method of gridding Mean Sea Sureface Height data using the SVR method. The radius is deter- mined by analyzing the characteristics of the Mean Sea Surface Height data. The Mean Sea Surface Height data is gridded by u- sing the Surfer 11 software and the cross-validation is processed. The data gridded by SVR is compared with the data gridded by the Surfer 11 software. The analysis of the comparison results shows that this method is practicable.
