摘要
用连续曲率张力样条方法和Shepard方法分别对多颗卫星和单颗卫星的海面高数据进行格网化,得到平均海面高。将平均海面高与DNSC08、KMSS04、CLS01平均海面高模型进行了比较,分析了两种格网化方法的优劣。结果表明,连续曲率张力样条方法比Shepard方法更适合于卫星测高数据的格网化。
Sea surface height derived from single satellite and multi satellites was gridded using the methods of continuous curvature splines in tension and shepard respectively. The gridding result was compared with DNSC08 ,KMSS04 mean sea surface model and the advantages and disadvantages of the two methods was analyzed. The result suggests that continuous curvature splines in tension method is better for gridding satellite altimetry data.
