| 摘 要： | SRTM全球数字高程模型数据目前已被广泛应用于多个领域。最新版本的SRTM DEM仍然存在较小的高程空值区域（数据空洞）和模糊区域。文章在模拟某试验区域SRTM DEM数据空洞的基础上,利用线性插值、反距离权插值、二次多项式插值、三次样条插值等DEM插值方法进行了数据空洞的插值填补试验和对比分析,结果表明在丘陵地区和空...

| Abstract: | SRTM global digital elevation model data has been widely used in many fields.There are still some a few of elevation null regions(data hole)and fuzzy regions in the latest version of the SRTM DEM.In this paper,based on the simulation of the SRTM DEM data hole of a test area,using the methods of Linear Interpolation,Inverse Distance to a Power,Quadratic Polynomial Interpolation,Cubic Spline Interpolation and some other DEM interpolation methods,a test and a comparative study of the interpolation to fill data... |
