Paper Abstract

Aiming for steep terrain relief and complex geomorphic types, the practical airborne SAR mapping system (SARMapper) of China developed by a group led by CASM was constructed. SARMapper consists of hardware and software mapping system. In this paper, some new methods and mapping technical flow were proposed aiming for difficult terrain area in the process of developing mapping software system. Several key technologies and solutions were studies, such as DEM extraction through refined interferometry, stereogrammetry, and DEM fusion, Digital Orthophoto Map (DOM) generation with single/multi-polarization SAR images acquired from multi-direction, Digital Line Graphic map (DLG) generation under stereo-environment. Then SAR mapping workstation is used to map in such a large area. And then the comprehensive experiment in Qinling Mountain Area was carried on including interferometric parameters calibration, different resolution of airborne SAR data acquisition and mapping production generation. Experimental results have proved that these productions could satisfy the mapping accuracy of 1:10000 and 1:50000.
