21st Century Geology as a Data Science about Earth

The dividing by centuries is somewhat arbitrary and satellite interferometry has been in use since the late 1980s, but high-quality data only became widely available in the 2000s. Three-dimensional models are also not a novelty, and they have been created for a very long time — after all, the flat Earth on three whales is quite a volumetric model. So, what is the difference between the geology of the previous century and the present one? <img alt="" src="https://miro.medium.com/v2/resize:fit:630/0*npFlTDHdsWYqWNT9.jpeg" style="height:311px; width:700px" /> On the left is a fragment of the US geological map; on the right is a 3D geological model with an interferogram on the surface of the relief based on radar satellite imagery (the Density Gradient scale, %, represents the heterogeneity of geological density, and Band Magnitude denotes the phase difference of the reflected radar signal for a pair of temporally separated images). <a href="https://medium.com/@pechnikov/21st-century-geology-as-a-data-science-about-earth-c8304ab2bab4">Website</a>
