To achieve the high?efficiency management and 3D visualization function for multispectral remote sensing images, a method for the 3D visualized system design and realization of multispectral remote sensing images based on OpenGIS is presented. It builds the spatial database with PostgreSQL and PostGIS, releases the codes for web map service ( WMS) and web feature service ( WFS) by GeoServer, and realizes the three?dimensional display of the image and vector information on the visualized platform of World Wind. The results of three?dimensional visual?ization experiment on TM image show that the scheme has advantages of high efficiency, good visual effect and strong scalability, meeting the requirements of multispectral image data management and three?dimensional visual?ization business application.
