摘要
以等高线为例,探讨了利用地图等高线矢量化生产DEM内插算法,并分析了各种方法的精度及适用范围。
Interpolation is an important part in digital elevation model （DEM） production, which processes in DEM generation, quality control, accuracy assessment, application and so on. It describes several interpolation algorithms of DEM based on map contour, and discusses their accuracy and applicability.
