Abstract

Airborne LiDAR sounding technology is considered to be a promising new technique for earth observation. In China, most of the LiDAR sounding experiments were conducted in areas with relatively clear water quality, such as the South China Sea. This is the first time to introduce the advanced CZMIL(Coastal Zone Mapping and Imaging LiDAR) system in China. The Luoma Lake in Jiangsu Province was selected for experimental area. The test results show that although the survey area has low bottom reflectivity and high bottom reflection diffuse attenuation coefficient, CZMIL system can successfully detect the bottom data. The accuracy of result can meet the accuracy requirement of CZMIL system. The CZMIL system has better detection ability and precision.

Key words
