What Is A Bathymetric Map

Bathymetric maps are used in the exploration for minerals, the fishing industry, and as an important aid to navigation. These maps use color to indicate water depth. In case you don’t already know, bathymetric maps are based on bathymetry, which is, according to noaa (the national oceanic and atmospheric administration), the study of the ‘beds’ or ‘floors’ of water bodies, including oceans, rivers, streams and lakes.

How is bathymetry represented in the ocean tracks map? However, the principal technique for expressing the submarine topography involves drawing contour lines that connect all measured and extrapolated points. Bathymetry is the measurement of how deep the water is at various places and the shape of the land underwater.

What Is A Bathymetric Map Bathymetry is the study and mapping of the sea floor.

The grids are available to download or access through web map services. Bathymetry (/ b ə ˈ θ ɪ m ə t r i /; Gebco produces and makes available a range of bathymetric data sets and products. The bathymetry data layer shows the features on the ocean floor that you would see if you drained away all of the water.
