IHO Standards for Hydrographic Surveys (S-44)

The IHO Standards for Hydrographic Surveys, known as S-44, are guidelines set by the International Hydrographic Organization to ensure the quality and accuracy of data collected in marine surveys. These standards help surveyors measure the underwater landscape, map seafloors, and identify navigational hazards. By providing specific criteria for survey techniques, equipment, and data interpretation, S-44 aims to enhance safety for maritime navigation and improve the overall understanding of oceanic environments, thereby supporting shipping, research, and environmental protection efforts.
