In that technology satellites use radars and meters range between satellite and planet, what makes possible to make those maps, and modern computers and radars allow to make high-resolution 3D-maps, what can be zoom in very good accuracy. By using VLF or ELF (Very or Extra Long Frequency) radars those satellites can make 3D maps from the ocean floor from the orbital trajectory. Same way ships can make 3D maps from the ocean floor, by using sonar systems. Also, Lidar or laser radars can be used in those mapping operations. Blue-green laser radars can scan very deep areas of the oceans, and that equipment can also meter the altitude and length of the waves. But now I missed the thing, what I suppose to write. If the mobile telephones would be connected to dron...
