50 years ago, NASA launched Nimbus to study Earth from space. Now, experts at the National Snow and Ice Data Center (part of CIRES), are recovering valuable data and images from old, long-lost film, and expanding their understanding of sea ice in the Arctic and Antarctic. Learn more from CIRES on the 1-year anniversary of Nimbus' first image:

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.
