Planet Action 2012 Annual Report

p183_58d646b294dd4ce3cb91539f9cb444d22012_-_PA_Annual_Report_Page_01

Planet Action is a non-profit initiative launched in June 2007 by Spot Image. It has been joined by ESRI as a co-founding partner very early, and other partners have also joined the initiative since. More recently, Planet Action and the UNESCO signed a cooperation agreement within the framework of the Open Initiative to support World Heritage sites.

Man-made climate change is a global issue with serious threats: this is a new challenge for our societies and communities to get fully involved with new and cooperative approaches.

It is our ambition, as a committed and responsible corporate citizen, to bring quality technologies and expertise to the non-profit community working on climate change.

The projects benefiting from Planet Action grants reflect the complexity and interactions at stake in shaping a future based on sustainability.  We are grateful to them for their work and feedback.  We also appreciate the strong relationships that help us share knowledge within the Planet Action’s community: non-profits and NGOs, technology providers (ESRI, ITT, Trimble), experts, and outreach partners.

We hope this Annual Report presents an accurate picture of our activity and our personality.

The Planet Action team

GMES Land geoland2 Project: An Era Ends

After 8 years of GMES land research projects and the start of the initial GMES Services (GIO) in 2011, two important events signaled the transition from prototype development to operational implementation of land services: (1) the 8th and last “geoland forum2:http://www.gmes-geoland.info/news-events/geoland-forums.html in Copenhagen and (2) the final review meeting in Brussels.

The geoland2 project with 57 partners from 20 European nations developed the GMES Land Service and demonstrated an impressive portfolio consisting of 200 different products and applications. The continental and local component of geoland2 were transferred to the European Environment Agency and the global component to the JRC and implemented as part of GIO. Thus GMES Land leads – based on geoland2 results – to operational geo-information services that provide accurate, reliable and harmonised information across borders.

The 8th geoland forum took place in Copenhagen on 18th and 19th October 2012. 150 GMES Land stakeholders were invited to discuss the status and results of the GMES Land Services with the project consortium.

On 11th and 12th December 2012 the geoland2 project completed its final review meeting at the European Commission in Brussels. The project’s Executive Board presented the various results that have been achieved in the previous 4 years to the project officer and the review panel. During the two days intense meeting the team convinced the review panel that geoland2 has done a great job, in fact the European Commission was very impressed by what geoland2 has delivered.

CryoSat Hits Land

MATLAB Handle Graphics

ESA’s ice mission is now giving scientists a closer look at oceans, coastal areas, inland water bodies and even land, reaching above and beyond its original objectives.

Launched in 2010, the polar-orbiting CryoSat was developed to measure the changes in the thickness of polar sea ice, the elevation of the ice sheets that blanket Greenland and Antarctica, and mountain glaciers.

The satellite’s radar altimeter not only detects tiny variations in the height of the ice, it also measures sea level and the sea ice’s height above water to derive sea-ice thickness with an unprecedented accuracy.

At a higher precision than previous altimeters, CryoSat’s measurements of sea level are improving the quality of the model forecasts. Small, local phenomena in the ocean surface like eddies can be detected and analysed.

300 m resolution

Taking CryoSat a step further, scientists have now discovered that the altimetry readings have the potential to map sea level closer to the coast, and even greater capabilities to profile land surfaces and inland water targets such as small lakes, rivers and their intricate tributaries.

Radar altimeters have more difficulty doing this because, compared to open ocean measurements, the landscape surrounding inland water bodies is a lot more complex.

These had not been previously monitored with satisfying accuracy by conventional altimeters because the sensor footprints – about 5×5 km – were too large to detect subtle differences in the topography around small landforms.

CryoSat, however, has a resolution along its ground track of about 300 m.

In order to thoroughly investigate the possibilities offered by CryoSat over water, ESA recently began scientific exploitation projects coined ‘CryoSat+’.

Scientists are reprocessing large, raw and uncompressed sets of data coming directly from CryoSat to obtain new information on oceans, inland water bodies and land.

In the example pictured above, CryoSat’s altimeter made readings over central Cuba, extending north and south into the surrounding water.

The image clearly shows the difference between the bright radar reflections from the steady water and the elevated land.

For instance, near the edges of the island, points of high radar reflection are pictured in red. This is due to the more placid waters of the bay and over coral reefs.

Examples are also pictured over the Danube delta in eastern Romania, and the land-locked Issyk Kul lake in Kyrgyzstan.

“Thanks to CryoSat being operated over some inland water targets in high resolution mode, we were able to distinctly chart the contours of a flood that occurred last March at Rio Negro in the Amazon,” said Salvatore Dinardo, working for ESA on CryoSat+.

Jérôme Benveniste, the ESA scientist who initiated the project, continued, “We were able to emphasise the unique capability to see the floodwater extent under the forest canopy, where optical sensors or even imaging radars are blocked by the trees.”

Results from the project will be unveiled to the scientific community at the Third CryoSat User Workshop to be held in Germany at the Technical University of Dresden on 12–14 March.

Monitoring Water Resources in the Mediterranean

Rice_mapping_node_full_image

The effects of climate change, population growth and economic development in the Mediterranean are posing a threat to the water supply in the region. As part of ESA’s TIGER initiative, satellite data are supporting water management by identifying water resources.

The demand for water is growing around the Mediterranean and is especially crucial in areas that do not receive regular rainfall. This is especially true for the southernmost parts of Europe and the countries lying along the African coast and in the eastern Mediterranean Basin.

Owing to the increasing population, the demand for water is growing for drinking and irrigation, representing 70–80% of the water use in the region. To get a better grip on water management, satellites are increasingly acknowledged as indispensable tools for collecting information on available water resources and their use.

This information is also necessary for planning infrastructure, such as where to build a dam, how to divert a waterway or manage a flood event.

The ten-year TIGER initiative exploits Earth observation technologies in order to respond to the urgent need for reliable water information in Africa.

TIGER is currently collaborating with the Euro-Mediterranean Information System on Know-How in the Water Sector (EMWIS), organising water observation systems and building capacity in the Mediterranean region.

In this context, a short training session and workshop was organised in early December at ESA’s ESRIN centre in Frascati, Italy, with participants representing national water authorities and remote sensing institutions from Morocco, Tunisia, Egypt, Lebanon and Jordan.

Nile encroachment

“The collaboration initiated with ESA is very promising,” said Eric Mino, manager of EMWIS Technical Unit.

“Earth observation can not only increase knowledge on the water cycle and irrigation efficiency at river basin level, but also provides comparable, independent and objective information across the boundaries.

“This is necessary for all international water initiatives in the Mediterranean region, in particular for the projects initiated by the Union for the Mediterranean.”

In Egypt, satellite data are being used for monitoring rice fields – a crop that requires a significant amount of water and is mainly grown in the Nile Delta. Satellite observation on land cover maps combined with indicators on the vegetation status and land-surface temperature help to improve crop irrigation management.

Between Egypt’s arid climate and high water consumption, it is important to keep an eye on water quantity, as well as quality. To estimate the quantity lost by evaporation, information on land-surface temperature is used based on satellite data.

Satellite imagery is also used to observe wetland environments and monitor changes in coastlines and river banks, such as the Nile.

High-resolution imagery from the upcoming Sentinel-2 mission, being developed under Europe’s Global Monitoring for Environment and Security (GMES) programme, is expected to improve crop mapping and support water management in the Mediterranean Basin.

Researchers Snow-Covered Desert

717023main_desert_snow_covered_cropped_946-710

Snow-covered deserts are rare, but that’s exactly what the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite observed as it passed over the Taklimakan Desert in western China on Jan. 2, 2013. Snow has covered much of the desert since a storm blew through the area on Dec. 26. The day after the storm, Chinese Central Television (CNTV) reported that the Xinjian Uygyr autonomous region was one of the areas hardest hit.

The Taklimakan is one of the world’s largest—and hottest—sandy deserts. Water flowing into the Tarim Basin has no outlet, so over the years, sediments have steadily accumulated. In parts of the desert, sand can pile up to 300 meters (roughly 1,000 feet) high. The mountains that enclose the sea of sand—the Tien Shan in the north and the Kunlun Shan in the south—were also covered with what appeared to be a significantly thicker layer of snow in January 2013.
