摘要
在GIS的研究中,通常需要具有一定规则的数据,而多数可获得的数据都是呈现离散状态并且是不规则分布的,这就需要应用空间插值的方法把离散的不规则数据转换成规则数据。本文介绍了几种常用的空间插值模型的原理与方法,并通过规则格网DEM的建立,说明空间插值算法在GIS中的应用。
Data that has certain rules is needed on the research of GIS, but in most cases the data we can get directly is discrete and irregular. So we need to convert data which is discrete and irregular to the one has certain rules through the spatial interpolation. Com- mon interpolation methods are described in this paper. And then the application of the Spatial Interpolation methods in GIS is intro- duced through the creation of DEM.
