Successful Pleiades 1A Launch

The successful launch Dec. 16 of the French Pleiades 1A high-resolution civil/military optical Earth observation satellite was accompanied by several minutes of tense silence as mission control at Europe’s Guiana Space Center here awaited word from Moscow that Pleiades had been released into orbit.

In one of many examples of what it means to import Russia’s Soyuz rocket for use at Europe’s spaceport, it is Moscow, and not the launch control facility here, that received telemetry confirmation from the vehicle’s Fregat upper stage that the satellite was separated as planned into a 700-kilometer polar low Earth orbit.

Satellite evidence for a large source of formic acid from boreal and tropical forests

Formic acid contributes significantly to acid rain in remote environments. Direct sources of formic acid include human activities, biomass burning and plant leaves. Aside from these direct sources, sunlight-induced oxidation of non-methane hydrocarbons (largely of biogenic origin) is probably the largest source. However, model simulations substantially underpredict atmospheric formic acid levels, indicating that not all sources have been included in the models. Here, we use satellite measurements of formic acid concentrations to constrain model simulations of the global formic acid budget. According to our simulations, 100–120 Tg of formic acid is produced annually, which is two to three times more than that estimated from known sources. We show that 90% of the formic acid produced is biogenic in origin, and largely sourced from tropical and boreal forests. We suggest that terpenoids—volatile organic compounds released by plants—are the predominant precursors. Model comparisons with independent observations of formic acid strengthen our conclusions, and provide indirect validation for the satellite measurements. Finally, we show that the larger formic acid emissions have a substantial impact on rainwater acidity, especially over boreal forests in the summer, where formic acid reduces pH by 0.25–0.5.

2011 Antarctic Ozone Minimum

Scientists from NASA and the National Oceanic and Atmospheric Administration confirmed today that ozone depletion over the South Pole in 2011 has reached its annual maximum. Researchers used satellites, ground based monitors, and instrumented balloons to observe the hole, finding it to be among the top 10 worst for the breadth and depth of ozone loss in the 26 year record.

The south pole-centered map above is based on data from the Ozone Monitoring Instrument (OMI) on the Aura satellite. OMI is a spectrometer, built for the NASA satellite by scientists in Denmark and Finland, that measures the amount of sunlight scattered by Earth’s atmosphere and surface. OMI allows scientists to assess how much ozone is present at various altitudes—particularly the stratosphere—and near the ground.

CryoSat rocking and rolling

ESA’s ice satellite is rolling left and right in orbit to help it continue its precise measurements of the vast ice sheets that blanket Greenland and Antarctica.
 
Since its launch 18 months ago, CryoSat-2 has been collecting data to improve our understanding of the relationship between ice and climate.
Just this year, the first map of Arctic sea-ice thickness was unveiled, and the satellite will continue to monitor the changing ice for years to come.

See the Shrinking Arctic Sea Ice

The National Snow and Ice Data Center released preliminary numbers on the minimum extent of Arctic sea ice, calling this year’s minimum the second lowest on record. Other groups relying on slightly different data report this year’s sea ice minimum is a record low. At the end of the day, whether this year goes down as the lowest or the second lowest ice extent isn’t particularly important. The long-term trend is abundantly clear. Sea ice is retreating, and fast. NASA hasn’t weighed in officially with its numbers, but Goddard Space Flight Center’s Flickr page has posted striking video and stills of the 2011 ice loss.

Morganza Floodway after Five Days of Flow

Five days after the U.S. Army Corps of Engineers opened a flood control structure, or spillway, onto the Morganza Floodway, water had spread 15–20 miles (24–32 kilometers) southward across the Louisiana landscape.

As of May 18, 2011, a total of 17 bays on the spillway had been opened, with an estimated 114,000 cubic feet (3,200 cubic meters) per second flowing out of the Mississippi River and into the floodway. According to temporary gauges placed by the U.S. Geological Survey within the floodway, the water level at Tail Bay (the spillway) was 45.04 feet above sea level as of 3:00 p.m. Central Daylight Time on May 19. Downstream at U.S. Highway 190, the water level was 32.55 feet as of 3:40 p.m. CDT on May 19.

APEX, ESA’s first airborne imaging spectrometer

In December 2010, the Airborne Prism EXperiment (APEX) was officially accepted by ESA-PRODEX. This means that after a long development phase that started in the early 90’s, the instrument is now ready for operations. APEX has been developed by a Swiss-Belgian consortium led by the Remote Sensing Laboratories (RSL) at the University of Zurich and the Flemish Institute of Technological Research (VITO). The latter will be responsible for the airborne campaigns and the data processing, while RSL is primarily responsible for the scientific aspects.
 
APEX is intended as a simulator and a calibration/validation device for future spaceborne sensors. It is an advanced scientific instrument for the European remote sensing community, recording hyperspectral data in approximately 300 bands in the wavelength range between 400 nm and 2500 nm and at a spatial ground resolution of 2 to 5 m. Hyperspectral remote sensing or imaging spectroscopy greatly extends the scope of traditional remote sensing. It is based on the detection of many narrow, contiguous spectral bands. This presents opportunities for more precise identification of surface materials than is possible with broadband multispectral sensors. Possible applications are endless, but the most promising ones are in the field of geology, mineralogy, agriculture, vegetation analysis, aquatic monitoring (as well as snow & ice), and atmospheric applications.

Merger of Eurimage S.p.A into e-GEOS S.p.A

The Belgian Earth Observation Platform would like to inform you that since May 1st 2011 Eurimage S.p.A has been legally merged into e-GEOS S.p.A.

This merger is the consequence of some important changes within Eurimage and the Telespazio Group over the last two years.
The first change and probably the most imortant milestone was reached on July 1st 2009, with the transfer of the Telespazio Earth Observation (EO) Division into e-GEOS SpA and with the assignment of world-wide exclusive rights for the commercial distribution of COSMO-SkyMed data from the Italian Space Agency ASI to e-GEOS.
e-GEOS (owned 80% by Telespazio and 20% by ASI) holds not only commercial distribution rights for the 4 fully operational radar satellites of the COSMO-SkyMed constellation, but benefits from all other assets previously held by the Telespazio EO group. These assets include, among others:

• the exclusive distribution agreement with GeoEye Inc. for GeoEye-1 and IKONOS imagery in Europe and North Africa, also through the e-GEOS receiving and processing station in Neustrelitz (Germany)
• the master distribution agreement with DigitalGlobe Inc. for the commercialization of QuickBird, WorldView-1 and WorldView-2 satellites
• the agreement with MDA GSI for direct reception and distribution of Radarsat-1 and Radarsat-2 data, also through the e-GEOS receiving and processing station in Matera (Italy)
• the more than 20 years' experience of the  Telespazio EO Group in application development, image interpretation and processing, near-real-time services and other related remote sensing activities.
• The second milestone was achieved in November 2009 with Eurimage becoming a 100% e‑GEOS and Telespazio company. This already brought about a full integration of Eurimage and e-GEOS, with sharing of personnel, operational procedures, systems, tools and expertise.

Arctic Ice Gets a Check Up

Scientists tracking the annual maximum extent of Arctic sea ice said that 2011 was among the lowest ice extents measured since satellites began collecting the data in 1979. Using satellites to track Arctic ice and comparing it with data from previous years is one way that scientists track change in the Arctic system.

"For the first 20 years of the satellite record, the average annual maximum was basically uniform," said Joey Comiso of NASA's Goddard Space Flight Center in Greenbelt, Md., who studies the sea ice data collected by the AMSR-E microwave sensor on NASA's Aqua satellite. "Then, we see an abrupt decline."

Ocean Crossroads

It is a general rule of the ocean that phytoplankton grow best where nutrients swirl up from the depths and where temperatures are on the cooler side. That doesn’t mean floating marine plants cannot grow in any waters, but the most bountiful feasts of phytoplankton—and therefore, the best fisheries—tend to be in cooler, well-mixed waters.

These images show one of those rich mixing basins: the northwest Atlantic Ocean. Based on data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite, these maps show the concentration of chlorophyll (top) and sea surface temperatures (bottom) in the region from August 29 to September 5, 2010.

Record Melting in Greenland during 2010

2010 was an exceptional year for Greenland’s ice cap. Melting started early and stretched later in the year than usual. Little snow fell to replenish the losses. By the end of the season, much of southern Greenland had set a new record, with melting that lasted 50 days longer than average.

The image below was assembled from microwave data from the Special Sensor Microwave/Imager (SSM/I) of the Defense Meteorological Satellites Program. Snow and ice emit microwaves, but the signal is different for wet, melting snow than for dry. Marco Tedesco, a professor at the City College of New York, uses this difference to chart the number of days that snow is melting every year. This image above shows 2010 compared to the average number of melt days per year between 1979 and 2009.

Floods in Queensland due to heavy La Niña rains

Rivers in Australia’s Fitzroy Basin are swollen due to unusually heavy La Niña rains. The image below, taken by MODIS-Aqua, clearly shows the results. Damaging floods hit the city of Rockhampton, the pale tan area that spans the Fitzroy River. The river’s straight, well-defined channel through the city indicates some measure of flood control. North of the city, however, the river burst its bank and surrounded Rockhampton on the northwest. Similar flooding appears to be happening south of the city, but clouds (turquoise and white) obscure the view. As of January 5, the swollen river had closed the airport and a highway south of the city, and forced about 500 people to evacuate flooded neighborhoods, reported the Australian Broadcasting Corporation (ABC) News.

Cold weather in US and Europe to be caused by Arctic Oscillation

The last few weeks have been exceptionally cold in both the US and Europe. Not so in Greenland, which recorded significantly higher-than-usual temperatures, resulting in increased melt of glaciers. Cause of this seeming contradiction is the Arctic Oscillation, a climate pattern that influences winter weather in the northern hemisphere. It describes the relationship between high pressure in the mid-latitudes and low pressure over the Arctic. When the pressure systems are weak, the difference between them is small, and air from the Arctic flows south, while warmer air seeps north.

The Gulf of Mexico oil spill couldn’t have occurred at a worse time for bluefin tuna: they had come to the area – a major spawning ground – to produce offspring. Satellites are helping assess the damage from the disaster on the fish’s spawning habitat.
 
The majestic Atlantic bluefin tuna, among the largest fish able to grow the size of a Volkswagen Beetle, come to the Gulf yearly from January to June. Their peak spawning time in the Gulf is April and May – just when some 10 million litres of oil a day was pouring into the water following the explosion of the Deepwater Horizon rig on 20 April.

Flooding in Pakistan

Comparison of satellite imagery sometimes is the best way to objectively demonstrate the scale of natural disasters.  Such is the case for the disastrous flood in Pakistan that started earlier this month.

Floods on the Indus River continued to surge downstream into southern Pakistan more than three weeks after the initial floods started. By August 19, 2010 the floods had started to reach the Kotri Barrage, an irrigation structure immediately north of Hyderabad. The Kotri Barrage is the final such structure before the river empties into the Arabian Sea.  The Landsat-5 image below shows the situation before the floods.

Psychological research regarding remote sensing

Human screening and interpretation is an indispensable component in many aspects of remote sensing image analysis. Human intervention is a requisite for visual image interpretation, where the interpreter actually performs the analysis. Even in computer-based digital image processing, human screening and interpretation is still needed at certain stages. Image (co)registration, for example, requires interactive selection of ground control points. Supervised image classification on the other hand, calls for algorithm training data, typically manually indicated polygons. Even highly automated photogrammetric operation or image fusion techniques are not fully operational without the intervention of a human interpreter. Next to the remote sensing domain, human intervention plays an important role in other types of geodata processing such as GIS and cartography.

Soetkin Gardin of the University of Ghent has developped a tool to look into the effects of personality on the performance of remote sensing specialists.

On thursday April 8th Cryosat-2 was finally launched. 

Finally, because the launch of Europe's first mission dedicated to studying the Earth’s ice was not exactly a smooth ride. Cryosat-1 was destroyed on launch in October 2005.  It took more than three years to build a second version of the satellite, Cryosat-2, which was originally planned to be launched somewhere in March 2009. Further delays moved that date to February 25th, which was again and for the final time postponed due to a concern related to the second stage steering engine of the Dnepr launcher.

On April 8th, 15:57 CEST, Cryosat-2 was launched from the Baikonur Cosmodrome in Kazakhstan, this time with no incidents.

NASA and NOAA's GOES-14 Satellite Takes First Full Disk Image

GREENBELT, Md. – The latest Geostationary Operational Environmental Satellite, GOES-14, provided its first visible full disk image of Earth on July 27, at 2:00 p.m. EDT. The prime instrument on GOES, called the Imager, is taking images of Earth with a 1 kilometer (km) or 0.62 mile resolution from an altitude of 36,000 km (22,240 miles) above Earth's surface, equivalent to taking a picture of a dime from a distance of seven football fields.

"The first GOES-14 visible full disk image shows little activity in the Atlantic Ocean and two tropical waves located in the East Pacific Ocean with a low probability of becoming a tropical cyclone. Numerous thunderstorms are seen scattered along the east coast and western Atlantic Ocean, with more significant rains and thunderstorms in the southeast Oklahoma and northeast Texas area," remarked Thomas Renkevens, a User Services Coordinator from the National Oceanic and Atmospheric Administration's (NOAA) National Environmental Satellite, Data and Information Service, Camp Springs, Md. "NOAA will continue to follow the tropical waves and thunderstorms for possible further development."

GeoEye-1 Satellite Launches Into Space

GeoEye, Inc. (NASDAQ: GEOY), a premier provider of satellite, aerial and geospatial information, announced today the successful launch and deployment of GeoEye-1, the world's highest resolution, commercial Earth-imaging satellite.

GeoEye's ground station in Norway relayed the downlink signal it received from GeoEye-1 confirming that the satellite successfully separated from the second stage of the launch vehicle and began automatically initializing its onboard systems.

GeoEye-1 will simultaneously collect 0.41-meter ground resolution black-and-white (panchromatic) images and 1.65-meter color (multispectral) images. Designed to take digital images of the Earth from 423 miles (681 kilometers) and moving at a speed of about four-and-a-half miles (seven kilometers) per second, the satellite camera can distinguish objects on the Earth's surface as small as 0.41-meter or 16 inches in size. Due to U.S. licensing restrictions, commercial customers will get access to imagery at half-meter ground resolution.

10 Years VEGETATION Conference

With the ever increasing awareness of environmental issues as evidenced by among others the Kyoto protocol and the GMES and GEO initiatives, monitoring the state of our planet is becoming more and more important.

For 10 years, the VEGETATION mission has played an important role in meeting this need for information by offering the international community high quality data from a truly global Earth Observing System, which uniquely acquires data of the entire terrestrial surface on a daily basis.

First and foremost the VEGETATION mission has been catering for the needs of operational users – both institutional and commercial - requesting data in near real time. Over the years more than 14261 Gigapixels of data have been distributed to 7500 users. As such, the VEGETATION mission is a prime example of what Europe wants to achieve through the GMES initiative: operationally available data for operational applications.
The scientific community, however, was not left out. From 2001 on, archived data could be downloaded for free fuelling many international research projects and resulting in an avalanche of scientific publications.

VEGETATION’s centralised archive houses processed data covering the equivalent of 40 000 times the Earth’s surface, providing unique time series of the state of the Earth’s vegetation worldwide.

Although the VEGETATION instruments are in good shape and data will be available for the foreseeable future, it is time to think about mid-term continuity of the data.

This conference will be a forum where system engineers, data users and policy makers can meet. It wants to look back at the past by commemorating the fine operational achievements yet at the same time intends to map the way ahead, with a VEGETATION follow-on mission and Sentinel 3 taking over.

GeoEye-1 scheduled for launch August 22, 2008

Resolution
GeoEye-1 will have the highest resolution of any commercial imaging system and be able to collect images with a ground resolution of 0.41-meters or 16 inches in the panchromatic or black and white mode. It will collect multispectral or color imagery at 1.65-meter resolution or about 64 inches, a factor of two better than existing commercial satellites with four-band multispectral imaging capabilities. While the satellite will be able to collect imagery at 0.41-meters, GeoEye's operating license from the U.S. Government requires re-sampling the imagery to 0.5-meter for all customers not explicitly granted a waiver by the U.S. Government.

Accuracy
Besides unsurpassed spatial resolution of 0.41-meters or about 16 inches, GeoEye-1 is designed to be able to offer three-meter geolocation accuracy, which means that customers can map natural and man-made features to within three meters (about 9 feet) of their actual location on the surface of the Earth without ground control points. This degree of inherent accuracy has never been achieved in any commercial imaging system and will remain unchallenged even when next-generation commercial systems are launched in the coming years.


GeoEye-1, a polar-orbiting satellite, will be able to revisit any point on Earth once every three days or sooner. Though it stands two stories high and weighs more than two tons, GeoEye-1 is designed to deftly train the ITT camera on multiple targets during a single orbital pass and is able to rotate or swivel forward, backward or side-to-side with robotic precision. This unrivaled agility will enable it to collect much more imagery during a single pass.

Frequency
GeoEye-1 will make 12 to 13 orbits per day flying at an altitude of 684 kilometers or 425 miles with an orbital velocity of about 7.5 km/sec or 16,800 mi/hr. Its sun-synchronous orbit allows it to pass over a given area at about 10:30 a.m. local time every day. Given its altitude and sun-synchronous orbit, field of view and superior resolution GeoEye-1 can “revisit” any point on the globe every three days or sooner, depending upon the required look angle. The satellite will complement GeoEye's current IKONOS system and will collect imagery about 40 percent faster for panchromatic and 25 percent faster for multispectral collections. Together, the IKONOS and GeoEye-1 satellites can collect almost one million sq km of imagery per day.

Workshop RIMS

Unmanned Aerial Vehicles (UAV) are a valuable missing link to the traditional platforms used in Remote Sensing, i.e. manned aircraft and satellites. UAV platforms allow for rapid deployment and near real-time product delivery. These qualities are basic requirements in many disaster management applications but can also be exploited in surveying and photogrammetric urban mapping projects.
The RIMS project partners (UGent, VITO, IncGEO) are in the process of prototyping end-to-end low budget UAV imaging systems. Within these prototyping activities, the RIMS-project focuses on the generic image processing workflow for UAV or manned missions where aerial imagery is collected and where automated processing is essential to quickly respond to the user’s need for information.
With this workshop, the RIMS project partners want to present the current status of the prototyping process by live demonstrations and discuss the results with potential users.
