| Abstract: | There are many algorithms of earthwork calculation. In this paper, we summarize the traditional algorithms based on profiles, analyzing the abuse of this method. According to the characteristic of underwater terrain analysis,a new algorithm is set up. We mainly introduce the theory of this algorithm directly based on TIN in the research. It has been applied in the spatial analysis of underwater terrain successfully and approved well by the application. |
