Design of remote sensing-based geographic information system

To deal with problems of traditional geographic information collection, such as low real-time, poor authenticity the data, and unclear description detailed areas, a design scheme remote sensing-based system is proposed. The mainly consists imaging processing, data storage management, scene control transmission module. By use sensing technology, reflected radiated electromagnetic waves target area are collected from long distance to form an image, hue–intensity–saturation (HIS) transformation method used enhance image definition. Weighted fusion algorithm adopted process details image. spatial database stores manages text respectively, establishes attribute self-correlation mechanism render ground objects in picture SketchUp software. Finally, using RS422 protocol transmit can achieve effect multi-purpose, anti-interference system. experimental results show that practical experience proposed excellent, presented clear, edge clearly visible, which provide users effective data.
