Abstract
This work has as objective builds a tool for Visualization and Simulation
of Naval Exercises in Real Marine Sceneries. This tool was developed
considering as the Brazilian Navy controls and it analyzes their exercises. The
Real Marine Scenery is described mainly by the use of an image file in the
format BSB (Maptech), format this adopted for reproduction of Nautical Chart
and used by several Institutes Hydrographic in the world, as: Argentina, Brazil,
Canada, Mexico, United States and other. This format allows the use of images
great resolution, that are geographic referred, that specifies the geodesic datum
source of the chart, that describes palettes of alternative colors for observation of
the chart and it uses a compression form and own decompression of the data. For
that, a detailed study of this format type is also described in this work, that
concentrates on the aspects of data compression, storage forms, color description
and geographical coordinates. The Real Marine Scenery is used as background,
where the exercises are visualized through the introduction of the ship profiles
based in the symbols adopted by the Brazilian Navy, considering the real
geographical coordinates defined by Global System Position (GPS). The
positioned points and the lines that describe the routes are vectorial elements that
are included in the raster chart. The study also presents an abbreviation revision
of the process of evolution of the navigation from the past to the Electronic
Chart at present time.
