A wide variety of climate and terrain conditions exist in the United States and optimal cartographic generalization techniques for one area of the country may not be suitable for another, particularly when working with surface hydrographic data. This paper presents generalization and data modelling to produce reduced scale versions of hydrographic data for a multi-resolution national data set, ...

Acoustic seabed classification technologies measure acoustic diversity in the seafloor and surficial substrate. This diversity is generally well correlated with both geology and those benthic species which are keyed to geologic and biotic components of the seafloor. Remote acoustic seabed classification has reached a level of maturity and acceptance in the ocean community such that it should be...

A hydrographic survey is a standardized procedure for collecting data the production of nautical charts and publications. It lengthy costly procedure, so carried out depending on capabilities organizations. known that relatively large parts world's oceans are very poorly covered by surveys. To increase amount collected, International Hydrographic Organization (IHO) has introduced concept crowds...
