Manual on Hydrography
The IHO manual on hydrography general objective is to provide knowledge on the concepts involed in hydrography as well as guidance to plan and execute hydrographic surveys. The manual is considered to be a profesional guide for hydrographic surveyors and a tool for teachers and students involed in hydrographic courses or programs. The preparation of this Manual started after the majority of IHO Member States (MS) responded in favour of proceeding with a project that could result in a Hydrographic Manual (1999). The IHB proposed then the establishment of a Working Group that met for the first time at the IHB premises, 20-22 June 2001, where the Table of Contents was agreed: Team Leaders were identified to deal with specific subjects, being responsible for the compilation of experts' contributions, and 2 work program was defined. In 2004 a second meeting took place to review the result obtained and decide on a draft version of the Manual, After collecting comments from MS, the final version was prepared and the IHO Manual on Hydrography was published. The Manual is considered to be a worthy product that contributes to the mission of the IHO, whose objectives are: The coordination of the activities of national hydrographic offices, The greatest possible uniformity in nautical charts and documents, The adoption of reliable and efficient methods of carrying out and exploiting hydrographic surveys, The development of the sciences in the field of hydrography and the technigues employed in descriptive oceanography. It has to be acknowledged that several Hydrographic Offices (HO) have made great efforts in preparing and keeping up to date their version of a Hydrographic Manual, almost since their establishment, but the resources, both, in time and manpower reguired for this activity have precluded severai HOs from continuing this practice, thus agreeing in the need to co-operate and co-ordinate the efforts for the preparation of an IHO Hydrographic Manual. A Manual that could be useful to everybody, containing specific aspects on hydrography and other matter only in general terms, as they are much more thoroughly covered in existing textbooks which refer to them in considerably greater detail. The content of this Manual is divided into seven chapters: Chapter 1 refers to the principles of hydrographic surveying, including its specifications, Chapter 2 refers to positioning: Chapter 3 to refers to depth determination, including both the principles and technigues used, Chapter 4 provides information on sea floor classification and object detection, Chapter 5 refers in particular to water levels and flow, Chapter 6 is devoted to topographic surveying applied to hydrography: Chapter 7 provides, in a structured way, complete details on hydrographic practice, Annexes with Acronyms, Bibliography and other relevant information.
