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.

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.
