摘要
数字地面模型的内插过程 ,实质是以取样点为已知数据用一定的数学方法进行内插加密运算 ,从而得到理想的接近实际的数学模型。本文用详细的理论对几种内插法进行了分析 。
The process of DTM interpolation is actually interpolating operation with some mathematical methods based on known data the sampling points to obtain perfecter DTM. This paper analyzes the methods of interpolating DTM, and the analysis will provide very useful references for the practical applications.
