| Abstract: | This paper mainly investigates the feasibility on the application of highresolution AIRSAR in the Surveying and Mapping, presenting the key procedures of data processing, such as data acquisition, imaging processing, preprocessing, geometry processing, merging processing, extracting the basic mapping elements such as road, railway, water area, vegetation, infield and residential area, and evaluating the precision. Then updating the topography and extracting change information. Experiment results preliminarily show that highresolution and high quality AIRSAR image data could make its application extensive in the field of Surveying and Mapping. |
