With a resolution as fine as 149 square meters per pixel, about equal to the areal footprint of an American single-family house, BOEM’s bathymetry map is at least 16 times higher in resolution than the map historically used for the northern GOM. Most of those house-sized pixels in the new map are 1, 2, and 3 kilometers deep under the water, and the product contains 1.4 billion of them, making this a gigapixel map.
