Bathymetric maps look a lot like topographic maps, which use lines to show the shape and elevation of land features.. On topographic maps, the lines connect points of equal elevation.On bathymetric maps, they connect points of equal depth. Ocean Floor Topography .

However, explorations in 1950 and beyond revealed a complex ocean floor consisting of two deep ocean basins. The resolution of the gridded data varies from true 2-minute for the Atlantic, Pacific, and Indian Ocean floors and all land masses to 5 minutes for the Arctic Ocean floor. A Geospatial Framework for the Coastal Zone National Needs identifies and suggests mechanisms for addressing national needs for spatial information in the coastal zone. The ocean floors contain dramatic landscapes – volcanic ridges, lofty peaks, wide plains and deep valleys. The Esri Map Book, Volume 28, shows how GIS enables change and provides innovative, spatially based solutions to wide-ranging issues, including those affecting business, the environment, utilities, transportation, and government.
