Radar satellite missions can measure millimetre-scale changes in Earth’s surface following an earthquake. On 24 August 2014, an earthquake struck California’s Napa Valley. By processing two images from the Sentinel-1A radar satellite, which were acquired on 7 August and 31 August 2014 over this wine-producing region, an 'interferogram' was generated showing ground deformation.

This video replaces an earlier upload demonstrating the extraction of 3D detail for buildings and/ or terrain from high resolution drone aerial photographs using photogrammetry and geo-referencing. This version includes high definition footage from a simulated autonomous circular aerial survey of an industrial asset, incorporating VidiAir's precision ground survey control points (significantly more accurate than Google Earth), EMF/ RF protection and laser range-finding with telemetry - an important consideration when flying in close proximity to structures/ obstacles, particularly in gusting winds.

“Mapping the Universe” with Daniel Eisenstein
2.32K Views0 Comments0 Likes
Galaxies are not scattered randomly throughout the universe. Instead, they group into stringy filaments that span hundreds of millions of light-years. How did such structure evolve from the bland primordial soup that followed the Big Bang? New clues are coming from an ambitious mapping project, the Sloan Digital Sky Survey, which has measured the distance to galaxies halfway across the observable universe. Daniel Eisenstein is director of the Sloan Digital Sky Survey III (SDSS-III) and a member of the National Academy of Sciences.
