摘要: 为得到样本空间内连续的栅格数据,以ANUDEM插值算法为基础,基于ArcGIS Engine组件进行二次开发,实现一种空间数据的批量插值方法。对样本空间内的离散测量数据进行检索,重新组织数据格式并进行批量插值操作,将结果以图形化的形式显示。在云南蒋家沟流域水文计算系统中的应用结果表明,利用该方法可得到大批量可信度较高的流域雨量分布数据。

Abstract: An ArcGIS Engine and ANUDEM algorithm based batch interpolating method is implemented to create continuous raster data from discrete spatial data. The program retrieves measured discrete data within research area, reorganizes the data form, carries out batch interpolating and display the result graphically. It is adopted by hydrological computational system of Jiangjia Basin in Yunnan and the application results show that the method can obtain a great mount of reliable rainfall distributing data.
