How GIS Helps Drive Hydrography Data
There are more high resolution maps of the Moon and Mars, than the seafloor. Largely because of high costs and challenges at every stage of data gathering and processing. However, GIS-driven technological innovations have the power to change this with improved navigation and positioning systems and geoprocessing in real time for faster accurate surveys.
