Interferometric Synthetic Aperture Radar is an effective technique to get Digital Elevation Model and orthophoto map.
干涉合成孔径雷达是获取场景数字高程模型和正射影像图的有效技术之一。
Thus, the paper gives the the concept of corresponding digital orthophoto map applying to stereo scene, and discusses the theory, characteristic, production and application in city management.
The 4d productions is the historic result of the developing of the surveying technical, which are digital orthophoto map, digital elevation model, digital raster map and digital line map.
