The invention discloses an implementation method of surveying topography and landform by using the Beidou satellite system. The method comprises the steps of template data construction and surveying comparison. The method utilizes wavebands transmitted from Beidou satellites to detect topography and terrain, and analyzes mineral resources and topographic and geomorphologic situations of the address on the basis of wavebands absorbed by objects according to waveband feedbacks. The method overcomes the problems that using high-definition photography for survey is high in cost and can be easily affected by visibility, realizes low-cost topographic and geomorphologic surveying, is high in stability and reliability, and has good economic and social benefits. The method can be widely applied to Beidou antenna topographic and geologic surveying systems.
