N2 - In this paper we consider variants of building efficient algorithms for processing, interpolation and visualization of the Earth's topography and bathymetry of the oceans, destined for realization of meteorological information system and direct computational experiments on modeling of ocean, offshore waters and coastal shallows hydrodynamics. The variants of advance preparation digital arrays in the representation of architecture IBM-PC type computers and huge volumes (about 15 GB) in the original NetCDF formats with hardware encoding VAX (PDP-11). In the coordinate transformation tensor operations are utilized for fast transitions between Mercator and geographical (spherical) projections. Direct encoding graphical fields is performed in a standard RGBi bitmap representation in main memory, that is required for activating the algorithms of parallel computing.
