Abstract: The mapping system integrated both up-water and under-water provides an efficient and rapid solution for water-related survey works. The study background on multi-sensor integration and data fusion was presented firstly. The primary theory and methodology of mapping system integrated both up-water and under-water was stated detailedly. Based on project test data, the accuracy statistics and analysis on point cloud data were worked out precisely. It was demonstrated that the proposed integrated mapping system would be an efficient solution and could satisfy the specification requirement of water conservancy and hydropower engineering project applications.

Key words: integrated survey system, multi-sensor integration, multi-data fusion, shipborne, mobile mapping
