The title of the 1st edition of S-44 which was published in 1968 was “Accuracy Standards Recommended for Hydrographic Surveys” and still highlights to this day the main focus of the standard. “This new edition is not a revolution, but represents nonetheless a real evolution and is a logical next step incorporating feedback we received from the hydrographic community and IHO stakeholders”Ĭhristophe Vrignaud of the French Hydrographic office (Shom), led the Hydrographic Surveys Project Team (HSPT) which had been tasked with updating the standards.
ACCURATE 4 STANDARD EDITION MANUAL
For procedures for setting up equipment, conducting surveys, and processing the resulting data, users can refer to the IHO Manual on Hydrography (Publication C-13). Hydrographic offices and organisations are able to define more stringent or specific requirements for national or regional variations when necessary. S-44 specifies the minimum standards to be achieved depending on the intended use. Since the cost of surveys can range in the millions of Euros, S-44 is an essential tool for all institutional and commercial surveyors.

ACCURATE 4 STANDARD EDITION SOFTWARE
“It is regarded as the reference for any contracted survey and provides the benchmark for the validation of results” ACCURATE Versi 4 Standard Edition Posted on 19 September 2011 by Accurate - Akuntansi Indonesia ACCURATE Accounting Software Versi 4 Standard Edition untuk Perusahaan Trading, Service dan sejenisnya, tampil dengan tampilan dan fitur baru yang lebih dinamis, lebih praktis, dan lebih interaktif dari ACCURATE Versi 3. “S-44 is the hidden champion amongst IHO´s technical standards” The aim is to allow flexibility in the survey definition and to accommodate these various needs as well as emerging technologies such as satellite derived bathymetry. In these specific areas, an increased accuracy of +/- 10 cm on a map can help precisely determine requirements for dredging and avoid unnecessary costs.Īnother key feature of this edition is a new “Specification Matrix”, a matrix of parameters and data types which defines the required accuracy depending on the hydrographic needs. This is designed for specific critical areas such as harbours and channels with minimum underkeel clearance and bottom characteristics which could be hazardous to vessels. One of the notable changes in this latest version is the introduction of a new more stringent classification for surveys called “Exclusive Order” which expands the standards' applicability. In addition to surveys to support the safety of navigation, these standards can be adapted for oil and gas, renewable energies, dredging, geophysics, and geotechnics.īy clarifying the required levels of accuracy, they will help define the requirements in terms of technology, time and human resources and will save valuable resources. The IHO released earlier this month a new edition of the Standards for Hydrographic surveys (S-44).
