Abstract:In order to strengthen the overall management and precise regulation of land reserve, improve the efficiency of land reserve potential area selection, research and accurate analysis, on the basis of discussing the advantages of multi rotor UAV in land reserve accurate analysis, a land reserve accurate analysis scheme based on multi rotor UAV technology has been proposed in this paper. Taking Ji'nan city as an example, by using new technologies of surveying and mapping geographic information comprehensively and innovatively, from the aspects of land reserve potential area identification, 3D model construction, building house information collection, economic analysis of reserve costs and benefits and archives management, accurate analysis of land reserve potential has been finished. It will provide an important technical support for land reserve management organization in Ji'nan city, form a "large group" and "large area" collection and storage mode, plan land reserve work as a whole, and laid a foundation for wide application of UAV aerial survey technology in land reserve.
