3D-Positioning and Mapping,The sequence of events that occurred as the Earth crust cooled is difficult to reconstruct. It is possible, however, that the Earth’s surface could still have been dominated by a salty ocean: a hydrosphere.arthroscopy 发表于 2025-3-28 19:08:30

ICT Applied to Sea Surveying,Together with ice, the liquid water covers over 70.6 % of the Earth’s surface, the hydrosphere. Despite great advances in hydrographic surveying and remote sensing techniques, this area cannot be easily mapped. The world’s oceans are the largest not fully explored regions in the world. It remains a major frontier in the third millennium.subacute 发表于 2025-3-29 16:22:08

Trusting Code and Trusting Hardware, go to the Moon to look at the true shape Earth, all early civilisations imagined the Earth as a flat disk, with peaks heaped upon it like food on the king’s table. Throughout the past five centuries, the mathematicians not only extended the subject vastly but, as they made successive extensions, as
