Ocean MAPs

Do we have some Technology that mapped all Oceans, Seas, Rivers, Canals on earth.

Just like we use Google Maps to traverse on earth, we should have some maps for Boats, Yachts, and SHIPs.

Probably those are LIDAR Maps, RADAR Maps, AIR Maps..

One day we would need 3D AIR maps as well for our DRONES to rule the 3D world out there.
