| Abstract: | This paper introduces the principle and the idea of constructing of DEM, and its application in the token of the seafloor topography. Analyzing the precision of submarine DEM based on the chart and concerning the loss of precision which is introduced by transforming of data, the paper puts forward an improved method and establishes the submarine DEM based on the original sounding lines. It analyzes the latter in theory and illustrates it. |

| Keywords: | structure of submarine DEM original data of sounding lines precision analysis |
