The factors affecting the accuracy of bathymetric survey were analyzed in this paper. The errors in bathymetric survey mainly include instrument error, velocity error, tidal observation error, ship speed error and vessel factors. Based on a comprehensive analysis of causes of the measurement errors, this paper puts forward measures to improve the measurement precision, gives examples and points out maters needing attention in application.
