Abstract: This paper briefly reviewed the history of seafloor terrain measuring technology,and then detailed the introduced sonar bathymetry based on vessel,airborne laser bathymetry,integrated measurement for coastal topography and three inversion methods for seafloor terrain.That entirely presents the current situation of stereoscopic,efficient,high-accuracy and high-resolution of seafloor topography acquirement.Finally,combined with the future requirements,this paper summarized the core job and development trend in future seafloor terrain measuring field,which includes developing more portable multi-beam system with ultra-wide coverage,high accuracy and resolution,researching more efficient correction model of sound velocity effects,smoothing of bathymetry data and expression of submarine topography.Meanwhile,automatic ship measurement will be an important task mode.Also airborne laser survey,seafloor topography inversion from sonar image and deep-towing measurement has enormous potential in development.

Key words: seafloor topography, stereoscopic survey, high resolution, high accuracy, current situation, development tendency
