| Abstract: | There are many difficulties in high-precision terrain mapping of uninhabited islands and beefs because of the complex environment and different datums.This paper introduces a surveying and mapping system for uninhabited islands and reefs based on drones and unmanned vessels.The results are obtained by means of geodetic surveying,drone aerial remote sensing,and unmanned vessel underwater surveying and mapping.Field surveys were carried out in the Triangular island of Zhuhai City,Guangdong Province,and the integrated three-dimensional point cloud,contour,DOM and other data of the island were obtained.The accuracy of the land-based results is up to the centimeter level.The results of water depth measurement meet the requirements of the regulations.The results can be widely used in the fields of ocean,land,surveying,mapping,planning,construction,etc,helping to solve the problems of low data accuracy caused by the lack of control points,as well as the problem of repeatedly collecting data due to different demands by various departments.It is proved that the technology has certain engineering significance. |
