IHO standards and specifications publications: :

The various publications of the International Hydrographic Organization (IHO) are grouped on this page and refer to PDF documents generally in English and French (official languages of the organization). Under the heading Standards and Specifications, you will find the catalogue of documents with the index “S-” which defines the standards of the profession.

OHI S-44 : IHO Standards for Hydrographic surveys – 5th edition, February 2008 ; 1Mo (ENG.)

This publication is part of the series of guides developed by the International Hydrographic Organization to help improve good practice. This reference document S-44 establishes a set of standards for the conduct of hydrographic surveys.

In particular – Chapter 1 – it classifies different survey orders to meet different navigational safety requirements. The required accuracies detailed in Table 1 are minimum requirements for each hydrographic survey need.

A revised standard in Index 6.0.0 is currently in preparation and is planned for 2020.

OHI C-13 :IHO Manual on Hydrography – 1st edition, February 2011 ; 8Mo (ENG.)

This publication is part of the series of guides developed by the International Hydrographic Organization to help improve good practice. Reference C-13 establishes a set of methods for conducting hydrographic surveys.

The overall objective of this document is to provide knowledge of hydrographic concepts and to serve as a professional guide for the organization and conduct of hydrographic surveys.

SHOM French standards and recommendations :

The hydrographic data base is continuously enriched by bathymetric surveys conducted by non-Shom entities. These surveys are subject to various controls before they can be used, in particular to update nautical documentation.

The standards and recommendations available on this page are intended for producers of bathymetric surveys in order to help them in the control of the execution of works at sea and the drafting of the final documents.

Guide Shom V1.1 : Guide pour la réalisation des levés hydrographiques V1.1 de Décembre 2019 ; 6Mo (FRA.)

This document presents the methodology adopted at Shom for the execution of a hydrographic survey. On the programme: presentation of hydrographic standards (international and Shom), preparation of a survey, data acquisition and processing, qualification of the work carried out.

Synthesis document of the Working Group “Qualité des informations hydrographiques” :

The AFHy (Association Francophone d’Hydrographie) – formerly APHy – is for all francophone stakeholders in the hydrographic community. With the aim of promoting the quality of hydrography, the association has drafted a document summarizing the recommendations established by the working group “Qualité des informations hydrographiques”.

Guide APHy V1.5 : Recommandations pour la conduite d’un levé bathymétrique réalisé dans le domaine portuaire, côtier ou fluvial (Version 1.5 d’ Octobre 2008 ; 1,5Mo (FRA.)

This document is intended for any company or service ordering or carrying out bathymetric surveys in the port, coastal or river area. It is intended as a reference which should enable hydrographers to better justify the quality of their work, guide project contractors in their request for proposal (drafting of specifications), in the choice of a service provider, and during the commissioning of the work.
