Exploring the Martian surface is limited to data provided from NASA, but that's not much of a limitation considering that it's unlikely that most of us will ever get to visit the Red Planet. The oceanic maps provide the capability to plunge to the floor of the sea, view exclusive content from the BBC and National Geographic, and explore shipwrecks like the Titanic in 3D. In addition to Earth cartography, you can also check out Google Ocean, historical Earth maps, and the surface of one of our closest neighbors, Mars. Accessible enough for casual users, Google has added features that make it a necessity for those whose topographic desires are more serious. Google Earth continues to set the mapping paradigm.
