Aiming at the problem that it is time and labor consuming of TV broadcasting frequency programming,the paper proposed a method of applying the theory and method of geographic information system(GIS)to TV broadcasting frequency programming.The spatial database of GIS was introduced to improve the data management of TV broadcasting stations.A wave broadcasting model was constructed using GIS to simulate transmission and coverage of radio waves in the real world.The result shows that the software of TV broadcasting frequency programming exhibits the relationship between different waves and shows the effects of programming.The research results have certain reference value of saving limited frequency resources and programming TV broadcasting frequencies more scientifically.
