Abstract Radial submarine sand ridges are large-sized sandy accumulation bodies in offshore area of northern Jiangsu. Because of their complicated hydrodynamic environment and geomorphology, it is very difficult to obtain the field investigation data. This paper is based on the color and texture reflected on the remote sensing image, Geomorphologic mapping was conducted in combination with the measured terrain data and historical charts as well as the historical geomorphological map. In addition, the spatial characteristics were analyzed. The results show that the use of remote sensing images to draw the geomorphologic map of radial submarine sand ridges can provide practical and reliable scientific basis not only for the study of the geomorphologic structure but also for the development and utilization of spatial resources.
