Scientific maps are designed to provide significant information on specific features of a geographical area.
The data obtained allows scientists to better understand the geological and oceangraphical context of the
islands, as shown in the charts of currents, the sea floor and tectonic situation. Today, most scientific maps
are derived from satellite data. Even maps of the seafloor are made from gravitmetric readings (from
differences in gravity from one place to the next) obtained via satellite (see Satellite Images).
