Resumen Since many of the attempts to introduce a universal hydrographic data format have failed or have been only partially successful, a different approach is proposed. Our solution is the Hydrographic Universal Data Description Language (HUDDL), a descriptive XML-based language that permits the creation of a standardized description of (past, present, and future) data formats, and allows for...

Hydrographic data, be it observational or averaged data, contain substantial regions having vertical density inversions. A new analytical conserved adjustment scheme has been developed on the base of conservation of heat, salt, and static stability for the whole water column with a predetermined (T, S) adjustment ratio. A set of well-posed combined linear and nonlinear algebraic equations has b...

The increasing availability of geospatial marine data provides an opportunity for hydrographic offices to contribute to the identification of “Potentially Polluting Marine Sites” (PPMS). These include shipwrecks, oil rigs, pipelines, and dumping areas. To adequately assess the environmental risk of these sites, relevant information must be collected and converted into a multi-scale geodatabase ...

Underwater landscape: The combination of advanced sonar and satellite technology can produce high-resolution 3D models of seascapes like this one in the Caribbean. However, for much of the sea fl oor, there is still insuffi cient data. (Source: http://pubs.usgs.gov/of/2004/1400/). The 7th International Geographic Congress, held at Berlin in 1899, gave the start signal for the mapping of the oce...

Safety navigation of vessels is always the most important issue in maritime field. Recently, according to increasing the use of electronic equipment onboard, the requests for safety related information services have been growing up. To support this, International Hydrographic Organization suggests the concept of common maritime data structure. Since 2010, S-100 standard and relative product spe...
