Abstract: In view of the problems of traditional geographic information collection, such as low real-time, poor data authenticity and unclear description of detail area, a design scheme of geographic information system based on remote sensing technology is proposed. It is mainly composed of information acquisition module, imaging processing module, data storage and management module, scene control module and data transmission module.Remote sensing technology is used to collect the reflected and radiated electromagnetic waves in the target area.Transformation is used to enhance the image clarity, and weighted fusion algorithm is used to process the image details. According to the respective storage and management, the attribute self association mechanism is established. The SketchUp software is used to render the ground objects in the picture to achieve the actual control of the virtual objects. Finally, the RS422 protocol is used to transmit information in the wireless office network realizing the multi-purpose effect of one machine and enhancing the anti-interference ability of the system. The experimental results show that the proposed system is excellent in practice, the presented geographic information image is clear, and the edge details can be clearly visible, providing users with effective geographic information data.
