Abstract: Depth is the basic element that reflects the undulating shape of the submarine topography, and it is an important reference for human beings to understand and utilize the ocean and make scientific decisions.Digital depth model is a digital representation of submarine topography fluctuations using discrete depth data. The digital depth model constructing technology is closely related to the quality, characteristics and application fields,which directly determines the reliability and accuracy of the representation of the submarine topography,and will have an important impact on the safety of ship navigation and other related applications,has always been the core content of the scientific research of hydrographic and cartographers as well as the production practice of marine surveying and mapping geographic information products.On the basis of summarizing the conceptual connotation of digital depth model, combined with the current status of digital depth model constructing technology at home and abroad, this paper focuses on the research progress and achievements of digital depth model in navigational and non-navigational fields, and the future development direction of digital depth model constructing technology is prospected.

Key words: submarine topographic representation, digital depth model, model constructing technology, navigational applications, non-navigational applications, research progress, prospect
