基于DEM模型的卫星影像提供了区域内的数字三维模型，在这个模型上开展送电线路的可研以及初设工作，具有效果比较突出的优点，以太中银送电线路为例，简要介绍了在适普软件平台上实现DEM模型和卫星影像的叠加过程，并分析了其产生的效果，以供参考。%On the basis of three-dimensional digital model provided within the region of DEM model satellite image, the paper launches preliminary work of transmission line on the model, its effect is obvious. Taking Taizhongyin transmission line as an example, it briefly introduces the superposi-tion process of realizing DEM model and satellite image on the supersoft platform, analyzes its effect, with a view to provide some guidance.
