Spatial Analysis of Bathymetric Data and
Sea GIS
The results of bathymetric or hydrographic surveys are produced in the form
of nautical charts, sailing charts, coastal charts, harbor charts, electronic nav-
igation charts, raster charts, etc. These charts in conjunction with computer
aided digital display and sensors make excellent navigation equipments such
as ECDIC (Electronic Chart Display and Information System), leveraging the
power of bathymetric information and sensor information for safe navigation
in deep sea. Therefore these systems are the best examples of manifestation of
spatial information systems used for navigation, guidance and
