摘要：This Paper describes a hybrid system on 3D city modeling, data management and visualization component for 3D GIS infrastructure. The framework obtained high efficiency, without compromising the detail and accuracy of the result .The method utilize multi source data – digital camera and laser scanner to provide data redundancy required by automation. Classification and segmentation can be processed by combined multispectral information which is provided by color aerial image and geometric information from a laser scanned point cloud. Laser Point provide heuristic clue and digital camera provide detailed texture and linear segment by multi- view feature matching. Finally we discuss the data structure used for storage ,efficient access , transmission ,and visualization of 3D data
