How the Moon Holds the Key to Improving Satellite Views of Earth

Many Earth observation satellites make use of an added ingredient to ensure reliable, good-quality environmental data: the Moon. While the surface of the Earth is ever changing, the face of the Moon has stayed the same for millions of years, apart from occasional meteoroid impacts. This makes the light reflecting from the lunar surface an ideal calibration source for optical Earth-observing instruments. Now an ESA-led project has plans to make it more useful still. An instrument has been placed high on the slopes of Mount Teide in Tenerife, above the majority of clouds and airborne dust, designed to measure nightly... (read more)

UltraCam Osprey Prime - A Sensor for Nadir and Oblique Imaging

Michael Gruber and Wolfgang Walcher of Microsoft’s UltraCam business unit describe the qualities of the latest Osprey aerial camera. UltraCam Osprey Prime is the second generation oblique aerial sensor from Microsoft’s UltraCam business unit. It was first introduced at the ASPRS in Louisville, Kentucky in March 2014. The design goal – to combine a high quality metric nadir camera and large 45° oblique sensor heads – was modified slightly from the UltraCam Osprey, its predecessor. The upgraded nadir subsystem produces a panchromatic high-resolution image, a true-colour RGB image and a near-infrared image. The four oblique true-colour camera heads are now... (read more)

DJI’s Metric Camera for Aerial Surveying

DJI has released the X4S camera, a lightweight version of the large aerial cameras carried in manned aircraft. How do aerial or metric cameras differ to a DSLR? An aerial mapping camera is primarily designed to have a low distortion metric lens and reliable construction to maintain its calibration. To achieve this the cameras have very few moving parts, particularly those that would affect the lens focal length. Aerial camera lenses are very high quality and virtually distortion free. This, and a constant lens focal length, means that every pixel is in the right place. 3D mapping from photogrammetry is based on... (read more)

Hydrographers Search for Savings - Ocean Business 2015

Ocean Business took place between 14-16 April at the National Oceanographic Centre in Southampton. There were over 300 exhibitors in two giant marquees, a three-day schedule of training and demonstration sessions and the Offshore Survey 15 Conference. Richard Groom reports for GW. The main event attracts fringe activities which this year included a Blue Economy Day jointly led by FIG and IHO, and a Maritime Autonomous Systems workshop which was held at the NOC’s new Marine Autonomous Robotic Systems Innovation Centre. Ocean Careers was another parallel event at which practising hydrographic surveyors gave students their insights into the industry and... (read more)

Landsat: the Cornerstone of Global Land Imaging

Advancing the Understanding of Planet Earth
The Landsat satellites provide an uninterrupted space-based data record of the Earth’s land surface to help advance scientific research towards understanding our changing planet. In this article, the authors look at how the use of data from Landsat satellites has evolved over time to become a cornerstone of global land imaging with broad societal benefits. They conclude that the Landsat archive is poised to shift into a more real-time monitoring capability to help further our understanding of a changing Earth. Since 1972, the Landsat satellites have provided an uninterrupted space-based data record of the Earth’s land surface to help advance... (read more)

Bluesky Uses Mobile Phones to Create 3D Maps

Aerial mapping company Bluesky has completed a research project backed by the UK government’s innovation agency, Innovate UK, to develop the use of mobile phones for capturing accurate 3D spatial information. The nine-month investigation focused on the use of standard smartphone technology to capture and calibrate video footage, then convert it to 3D information. Accurate measurements of essential infrastructure, such as overhead power lines and other utility facilities, could then be extracted using specially developed algorithms and workflows. Designed to provide an accurate record of the feature’s location and its environment, the Bluesky project is expected to appeal to electricity... (read more)
