SPOT 6/SPOT 7 constellation in place now, designed for unparalleled high-resolution national coverage

Airbus Defence and Space has published the first images obtained from the SPOT 7 satellite, a mere three days after its launch on 30 June. Over the last few hours, the entire chain – from satellite programming and image acquisition to telemetry reception and processing – was successfully put into operation to deliver these first spectacular images.

These images show highly diverse landscapes, revealing SPOT 7’s full potential in terms of natural resource and urban zone mapping and agri-environmental monitoring.

The SPOT 6/7 constellation is now in place and considerably improves the capabilities and performance offered by SPOT 5, which has been in operation since 2002 and which is scheduled to be decommissioned from commercial service during the first quarter of 2015. This new constellation offers a higher resolution, greater programming reactivity and a much higher volume of images acquired daily (in monoscopic or stereoscopic mode).

SPOT 6 and SPOT 7 mark the dawning of a new era for the SPOT family in forming a constellation of high-resolution Earth observation satellites phased at 180° in the same orbit. This means that each point on the globe can be revisited on a daily basis and wide areas covered in record time, all with an unparalleled level of precision. With both satellites in orbit, acquisition capacity will be boosted to six million square kilometres per day – an area ten times the size of France.

With the very-high-resolution twin satellites Pléiades 1A and 1B, SPOT 6 and now SPOT 7, Airbus Defence and Space’s optical satellite constellation will offer the company’s customers a high level of detail across wide areas, a highly reactive image programming service and unique surveillance and monitoring capabilities.

Sentinel-1 aids Balkans flood relief

Flood_map_node_full_image_2

Although not yet operational, the new Sentinel-1A satellite has provided radar data for mapping the floods in Bosnia and Herzegovina.

Heavy rainfall leading to widespread flooding and landslides has hit large parts of the Balkans, killing dozens of people and leaving hundreds of thousands displaced.

Jan Kucera of the Europan Commission’s Joint Research Centre is supervising the technical aspect of the Copernicus Emergency Management Service (EMS). While mapping the flooding in northeastern Bosnia and Herzegovina, ESA delivered a radar scan from Sentinel-1A: “I had a first look and discovered that we were missing an important flooded area visible in the middle of the image.”

Although the radar on Sentinel-1A is still being calibrated, the new information could be integrated into the Copernicus EMS flood maps of the Sava river in the Balatun area in Bosnia and Herzegovina.

“In emergency situations like these, it is important that we optimise all the available data to produce better maps for disaster relief efforts.”

The radar on Sentinel-1 is able to ‘see’ through clouds, rain and in darkness, making it particularly useful for monitoring floods. Images acquired before and after a flood offer immediate information on the extent of inundation and support assessments of property and environmental damage.

Sentinel-1A was launched on 3 April, and is the first in a fleet of Sentinel satellites developed for Europe’s Copernicus environment monitoring programme.

Sentinel-1A_scan_node_full_image_2

Sentinel-1A scan

Although the satellite is still being commissioned, this Balkan coverage is an early example of the kind of operational data the mission will provide for emergency response.

Once operational, Sentinel-1 will revolutionise the use of satellites in risk assessment management and emergency response with its provision of large amounts of radar data in a systematic fashion.

The new scans are also being used by the International Charter Space and Major Disasters, which was activated by the Russian risk management authorities involved in flood response in Serbia.

The Charter is an international collaboration between the owners and operators of Earth observation missions to provide rapid access to satellite data to help disaster management authorities.

Big Processing of Geospatial Data

Geospatial Data has always been Big Data. Now Big Data Analytics for geospatial data is available to allow users to analyze massive volumes of geospatial data. Petabyte archives for remotely sensed geodata were being planned in the 1980s, and growth has met expectations. Add to this the ever increasing volume and reliability of real time sensor observations, the need for high performance, big data analytics for modeling and simulation of geospatially enabled content is greater than ever. In the past, limited access to the processing power that makes high volume or high velocity collection of geospatial data useful for many applications has been a bottleneck.  Workstations capable of fast geometric processing of vector geodata brought a revolution in GIS. Now big processing through cloud computing and analytics can make greater sense of data and deliver the promised value of imagery and all other types of geospatial information.

Cloud initiatives have accelerated lightweight client access to powerful processing services hosted at remote locations.   The recent ESA/ESRIN “Big Data from Space” event addressed challenges posed by policies for dissemination, data search, sharing, transfer, mining, analysis, fusion and visualization. A wide range of topics, scenarios and technical resources were discussed. In addition to the projects discussed at that event, several other big data initiatives have been launched to increase capabilities to processing geospatial data: the European Commission’s Big Data Public Private Forum, the US National Science Foundation’s Big Data Science & Engineering, and the US Office of Science and Technology Policy’s (OSTP) Big Earth Data Initiative (BEDI).

The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, was carried in a specialized pod on NASA’s C-20A. The 29-day deployment ended May 6 when the aircraft returned to its base in Palmdale, California after 19 flights totaling 97 hours in the air.

This is the second consecutive year the UAVSAR team has conducted a campaign to study sites in Central and South America. Many of the flights imaged the Andean volcanic belt located in western South America.

“By combining images acquired in 2013 with the 2014 images, researchers will produce detailed surface motion measurements to improve volcanic deformation models,” said Naiara Pinto, the UAVSAR science coordinator from JPL’s Suborbital Radar Science and Engineering group.

In coordination with the volcano studies, the agency’s C-20A gathered data over Amazonian forests in Peru, agricultural sites in Chile and glaciers in the Chilean/Argentinian border region. These data will aid in algorithm development and sensor calibration activities, improving scientists’ ability to monitor and study Earth’s carbon and water cycles. All of these research projects involve Latin American institutions, including universities and hazard monitoring agencies.

NASA’s C-20A, the military designation for the Gulfstream III aircraft, features a high-precision autopilot designed and developed by engineers at NASA’s Armstrong Flight Research Center at Edwards Air Force Base, California, allowing the aircraft to fly the same flight lines this spring as those flown in 2013.

The Precision Platform Autopilot guides the aircraft by using a kinematic differential Global Positioning System developed by JPL in concert with the aircraft’s inertial navigation system to enable it to fly repeat paths to an accuracy of 15 feet or less. With the precision autopilot engaged, the synthetic aperture radar is able to acquire repeat-pass data that can measure land-surface changes within centimeters.

This mission was conducted under NASA’s Airborne Science Program.

NASA and its partners monitor Earth’s vital signs from land, air and space with a fleet of satellites and ambitious airborne and ground-based observation campaigns. NASA develops new ways to observe and study Earth’s interconnected natural systems with long-term data records and computer analysis tools to better see how our planet is changing. The agency shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.

A Closer Look at LDCM’s First Scene

Turning on new satellite instruments is like opening new eyes. The Landsat Data Continuity Mission (LDCM) released its first images of Earth, collected at 1:40 p.m. EDT on March 18. The first image shows the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. The natural-color image shows the green coniferous forest of the mountains coming down to the dormant brown plains. The cities of Cheyenne, Fort Collins, Loveland, Longmont, Boulder and Denver string out from north to south. Popcorn clouds dot the plains while more complete cloud cover obscures the mountains.

LDCM is a joint mission of NASA and the Department of Interior’s U.S. Geological Survey.

“It’s a really great day,” said Jeff Pedelty, an instrument scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md., who worked on the LDCM Operational Land Imager, or OLI instrument, that took the natural color image. He’s very impressed with the level of detail they can see with the advancements to the sensor. “It’s wonderful to see, there’s no doubt about it, and it’s a relief to know that this is going to work wonderfully in orbit.”

The natural color image showed the landscape in the colors our eyes would see, but Landsat sensors also have the ability to see wavelengths of light that our eyes cannot see. LDCM sees eleven bands within the electromagnetic spectrum, the range of wavelengths of light. OLI collects light reflected from Earth’s surface in nine of these bands. Wavelengths on the shorter side include the visible blue, green, and red bands. Wavelengths on the longer side include the near infrared and shortwave infrared.

LDCM’s second instrument, the Thermal Infrared Sensor (TIRS) detects light emitted from the surface in two even longer wavelengths called the thermal infrared. The intensity of the emitted light at the longer wavelengths measured by TIRS is a function of surface temperature. In the black-and-white image of the first thermal band on TIRS, warmer areas on the surface are brighter while cooler areas are dark.

The first thermal images seen by Dennis Reuter, TIRS instrument scientist at Goddard, were forwarded to him from the data processors. “To say it was exciting was an understatement,” said Reuter, who was blown away by the data quality. “Wow! This is beautiful!” he wrote in an email. “Look at those amazing clouds! And the detail!”

Clouds in the colder upper atmosphere stand out as black in stark contrast to a warmer ground surface background. The TIRS images were collected at exactly the same time and place as the OLI data, so all eleven bands can be used together.

The infrared bands on both TIRS and OLI complement the visible bands, said Reuter. “You’re seeing things in the visible that you don’t necessarily see in the infrared, and vice versa,” he said.

China to Launch Earth Observation Satellite this Month

China-To-Launch-Earth-Observation-Satellite-This-Month

China is planning to launch a high-resolution Earth observation satellite this month, according to the State Administration of Science, Technology and Industry for National Defense (SATIND).

The government agency revealed details about the launch on Thursday, which was carried by the state-run Xinhua news agency.

The satellite will be the first to provide high-resolution observation data of the Earth. It will be launched using a Long March 2D carrier rocket, the SATIND said, and examinations of both the satellite and its carrier rocket have been completed.

China plans to launch five to six satellites by the end of 2015 in order to build a complete spatial, temporal, and spectral high-resolution observation system, Xinhua reported.

Data collected by the satellites will be used by the Ministry of Land and Resources, Ministry of Agriculture, and Ministry of Environmental Protection for disaster management, geographic and oceanic surveys, urban transportation management, and national security, the agency said.

DigitalGlobe’s WorldView-3 Satellite Continues on Track for Mid-2014 Launch

DigitalGlobenews-room

Company Will Complete GeoEye-2 Satellite to Preserve as Ground Spare

LONGMONT, CO–(Marketwire – Feb 4, 2013) – DigitalGlobe, Inc. (NYSE: DGI) (“DigitalGlobe”) today announced that its previously planned satellite construction program related to its third WorldView-class satellite remains on track.

DigitalGlobe can now confirm that it plans to complete WorldView-3 on its original schedule to be ready for launch in mid-2014 in order to meet the requirements of its EnhancedView contract with the U.S. government. That contract calls for completion and launch of WorldView-3, which will offer the most spectral diversity available commercially and be the first to offer multiple Short-Wave Infrared bands that allow for accurate imaging through haze, fog, dust, smoke and other air-born particulates. DigitalGlobe’s largest customer, the National Geospatial-Intelligence Agency (NGA), has confirmed the requirements of DigitalGlobe’s EnhancedView contract remain unchanged.

Accordingly, following its just completed combination with GeoEye, DigitalGlobe intends to complete the construction of GeoEye-2 in 2013 and to preserve it as a ground spare to meet customer demand or as a replacement for other on-orbit satellites. Previously, GeoEye had expected to launch GeoEye-2 in 2013.

“After careful consideration and discussions with our largest customer and others, we have determined that launching WorldView-3 and preserving GeoEye-2 as a ground spare will best meet the collective needs of customers and shareowners alike,” said Jeffrey R. Tarr, President and Chief Executive Officer. “This plan reduces our risk profile and capital footprint, while giving our customers access to the most advanced earth observation capabilities available commercially. Furthermore, as we move forward, if demand exceeds our expectations, we will be well positioned to quickly expand our constellation. GeoEye-2 and WorldView-3 are extraordinary satellites, and I want to thank all of our team members and partners for their continued efforts toward their completion.”

Since completing its combination with GeoEye, DigitalGlobe now provides customers with access to a constellation of five earth observation satellites and a broad suite of high-value geospatial production and analytic services. Customers will benefit from a larger constellation with optimized orbits, and coordinated scheduling will collect imagery faster, increase persistence and enhance resilience.

DigitalGlobe intends to provide full-year 2013 financial guidance and an updated capital expenditure forecast when it announces fourth quarter 2012 and full year 2012 earnings on February 26, 2013.
