Research on matching method of DSM in alpine shadow region
To address the unsatisfactory results of matching digitial surface model(DSM)in alpine shadow region in global mapping projects,this paper tests several combinations of key parameters in both CIPS and INPHO software,proposes a combination of software and parameters suitable for DSM data in shaded areas in alpine.By conducting production trials over an area approximately 5 000 km2 in the Greater Cau-casus Mountains of Russia and evaluating the results quantitatively and qualitatively.The experimental results show that the combination of using a 7 × 7 filter window in the CIPS software and Shuttle Radar Topography Mission(SRTM)assisting can effectively reduce the noise and topographic loss of the matching results in alpine shadow region,reasonably represent the shadow reigon,optimised the DSM matching process and effectively improve the vertical accaraly of DSM.
