多级空间数据插值及其应用方法

Multi-level Spatial Data Interpolation Methods and Application

分析了海量空间数据信息所面临的数据质量问题,对普通的空间插值方法进行了总结,提出了多级空间插值方法,并给出详细的算法流程.结合三维地质体建模进行了相关实验研究,结果表明多级插值可以保留三维地质模型的更多模型细节.

The quality of huge scale spatial data is specified with interpolation.Based on the analysis of normal spatial data interpolation methods,a new method of multi-level spatial data interpolation is proposed with algorithm in details.The result of experiment based on 3D geoscience modeling shows that it can heep more modeling features.
