I combined the two maps in Gimp, a free photo-editing tool, to make a black and white bump map to define the model’s surface.įirst, I converted the bathymetry image to Grayscale, to remove the blue tones: You can spot the famous Mid-Atlantic Ridge as a paler line down the middle of the Atlantic ocean, and the Marianas Trench as a patch of deeper blue off Japan. In the maps they provide, blue to white shading indicates changes in slope or depth, from -8000m to 0m (surface). As NASA explains, bathymetry is the underwater equivalent of land topography. You will also spot that Antarctica and Greenland have a relatively high elevation compared to other land masses such as Australia - this is due to their layers of ice.īathymetry tells us the depths of different parts of the world’s oceans. Notice the palest parts of the image - the white line of the Andes Mountains down the eastern coast of South America, and the pale white patch of the Himalayan Plateau. The relief shading in this topographic map comes mostly from elevation data collected by space-based radars.

Shading indicates changes in slope or elevation. Topography tells us the height of the mountains on land, relative to sea level. NASA’s Blue Marble project is where I got the bathymetry and topography data from.
