Blue Edge Relief

The seafloor, on your map.

Relief is a custom bathymetry overlay rendered by Blue Edge from public NOAA data and related sources. It sits over Satellite or Hybrid, so you see the land you know and the bottom you don’t.

NOT FOR NAVIGATION. Blue Edge Relief is for situational awareness only. It isn’t a chart and may contain errors, gaps or interpolation. Use official NOAA charts and your vessel’s navigation equipment.

Detail you can read.

Zoom in far enough and individual features stand out. This is the stern section of the Wilkes-Barre, a public wreck off the Lower Keys, in Relief.
