This article introduces the progress of calculating icing value base on the sampling icing data of transmission line, the DEM and the factor of region-climate, using GIS Spatial Analyst tools and modeling tools, and Then we can obtain a regional Raster map of ice value by Spatial Interpolation Analyst; After that, according to the rule of icing area divided, we should get the GIS vec-tor layer of ice level map, serving for Electric power Design and the safe of power grid.
