摘要：Precise spatio-temporal model can make it easy to obtain precise temporal and spatial information just like the true world, and it is of much importance to the planning and designing of Civil Engineering, the directing of disaster prevention and the plotting of military action. And airborne SAR (Synthetic Aperture Radar) has an advantage of full-time available and high resolution. So, in this paper the method and the potential of utilizing airborne SAR imagery to retrieve the precise temporal and spatial information will be researched. First, this paper researches the primary factors to reconstruct the precise spatio-temporal model from high resolution airborne SAR imagery, from which the information and texture structure of those factors can be exacted, including Digital Elevation Model (DEM), buildings and vegetation. Then, integrating Temporal GIS (TGIS) into the spatial model, this paper describes the mathematic model of retrieving temporal and spatial landscape in the nature, and discussed in detail the relationships between the factors which constructing the mathematic model. At the same time it puts forward to a kind of method to reconstruct the precise 4.5 dimension model with temporal and spatial factors by Virtual Reality (VR) technique. Within this paper, the corresponding accuracy criterion and the potential of forecasting the future model with the relative multi-temporal airborne SAR imagery are discussed
