Research on DEM and DOM Generation with Airborne InSAR Data
Three-dimensional information of each point on the image can be obtained by high-precision positioning based on airborne synthetic aperture radar interferometry(InSAR) data and high-precision Digital Elevation Model(DEM),and Digital Orthophoto Map(DOM) can also be obtained.Hence,the highprecision positioning is an important means to solve topographic mapping in large area with few control points,and has important significance for the unexpected natural disaster monitoring and evaluation of rapid response and quantitative analysis.The airborne InSAR high-precision positioning experiment which covers 4 strips 76 scenes 472 square kilometers is completed based on 0.5 m resolution airborne InSAR data by using self-developed Airborne InSAR Positioning Software System in Jiangyou Sichuan province,and the result meets 1:10000 scale DEM and DOM mapping accuracy requirements.
