Satellites help reduce Amazon deforestation

The Brazilian National Institute for Space Research (better know as INPE) has placed a contract for a third year with DMC International Imaging Ltd to acquire high-resolution satellite images of the entire 5 million square kilometres of the Amazon rainforest. Since 2004 INPE’s programme to monitor deforestation has dramatically reduced the rate of logging from 27,000 sq.km. per year to about 10,000 sq.km. in 2007.

In order to rapidly identify areas of cover change, DMCii is contracted to provide three repeat coverages in 2007 (June-July, July-August, September-October). In 2005, and again in 2006, DMC imaged the whole Amazon Basin in 6 weeks to provide Brazil with vital information to help monitor deforestation and combat illegal logging.

DMC imagery is provided by the five-satellite international Disaster Monitoring Constellation (DMC). The DMC small satellites, built by Surrey Satellite Technology Ltd (SSTL), use wide area cameras to capture the high-resolution images. The latest satellite, built for China, was launched into the DMC on 27 October 2005. Two new DMC satellites will be launched in 2008 and a third in 2009.

Speaking at the Royal Society in London, 25th October, Dr. Gilberto Camâra, Director General of INPE said,
“The DMC data is an important affordable contribution to our assessment of deforestation of the Amazon rainforest. The constellation is able to rapidly acquire and deliver high quality imagery so that we have up-to-date information to focus our efforts. It is our intention to develop a long term relationship with DMC”


The increasing amount of DMC imagery required by INPE since 2005 demonstrates the value of rapid revisit imaging. When the new DMC satellites launch in 2008, these will add considerably to INPE’s ability to monitor and combat changes in the rainforest and their consequences for both the local people and the global climate.

The Brazilian National Institute for Space Research (INPE) help Brazilian society to benefit from new developments in space science and technology. This includes increasing Brazil's autonomy in a number of strategic areas, providing the means for Brazilian industry to participate and become competitive in the space area and encouraging the development and dissemination of space technology.

INPE has developed a near or almost real time monitoring application for deforestation detection known as the Real Time Deforestation Monitoring System (DETER) system. High-resolution imagery is needed when estimating the total area of deforestation and when identifying small clearings.

When it's not coordinating the response to natural disasters, DMC International Imaging Ltd (DMCii) supplies remote sensing data products and services for international Earth Observation (EO) markets. DMCii supplies programmed and archived optical satellite imagery provided by the multi-satellite Disaster Monitoring Constellation (DMC). DMC data is now used in a wide variety of commercial and government applications including agriculture, forestry and environmental mapping.

Satellites help save lives

Monday, October 22. 2007

The UK is taking charge of an international group providing satellite data to support disaster relief across the world. The British National Space Centre and DMC International Imaging Ltd (DMCii) will lead the International Charter “Space and Major Disasters” from October 2007 until April 2008.

The Charter was set up in 2000 to provide satellite data and imagery to help governments and aid agencies plan emergency relief following major disasters. It has provided valuable information to relief agencies after earthquakes, floods, landslides and volcanic eruptions.

When the Charter is activated, Earth observation satellites operated by 14 international organisations are made freely available. The satellites provide data which is then used to produce maps and other information for emergency response efforts.

The UK-built Disaster Monitoring Constellation (DMC) is a key member of the Charter. The five satellites were built by Surrey Satellite Technology Ltd and are owned individually by Algeria, China, Nigeria, Turkey and the UK.

DMCii will chair the Charter Secretariat. DMCii Managing Director David Hodgson said: “Imagery from the DMC has been provided for more than 50 disasters and is particularly valuable in monitoring fires and floods.

“DMCii is also proud to provide regular emergency on-call services to the Charter and to task the world’s Earth observing satellites in response to disasters.”

Minister for Science and Innovation Ian Pearson said: “The UK is proud to lead this important group. We often think of space as being somewhere to explore, but it can also bring enormous benefits to us here on Earth."

Disaster Monitoring is one of the more direct forms of benefit from space, making it easier for the public to comprehend. The Charter is frequently called into action, or in Charter terms "activated". Charter members have been called on 34 times so far this year including on 14 September after floods devastated 12 countries in West Africa. The Charter was also activated in the aftermath of Hurricane Felix which hit Nicaragua and Honduras on 4 September 2007. The UK has activated the Charter twice this summer following the floods in north and south west England. Satellite data and images were used to produce maps of the flooded areas to help the Environment Agency assess the full extent of the damage.

NigeriaSat-2 PDR gets thumbs up

Thursday, June 28. 2007

SSTL have successfully completed the Preliminary Design Review (PDR) for NigeriaSat-2. The 300kg satellite will provide Nigeria with valuable geographically referenced high-resolution satellite imaging for applications in mapping, water resources management, agricultural land use, population estimation, health hazard monitoring and disaster mitigation and management, and will enable Nigeria to join the second generation Disaster Monitoring Constellation (DMC).

The PDR marks a significant milestone for the project and reflects the confidence of Nigeria's National Space Research And Development Agency (NASDRA) that the design proposed by SSTL will achieve their mission objectives.

The next step for NigeriaSat-2 is the Critical Design Review (or CDR). In the interim, SSTL will finalise the design of the NigeriaSat-2 spacecraft and ground segment and plans for the full satellite manufacture will be implemented. This is an exciting period for the small satellite manufacturer, because NigeriaSat-2 will use a new, more agile satellite platform (pictured left).

The PDR included the kick-off for the NX spacecraft, which the Nigerian engineers being trained at SSTL and the University Of Surrey will build alongside NigeriaSat-2 under the supervision of SSTL engineers as part of their Know-How Transfer and Training (KHTT) scheme. The Nigerian engineers presented the work undertaken during their training at SSTL and are preparing for the next stage, Mission Design Review, which will take place in August.

Customer representatives from the National Space Research & Development Agency (NASRDA), along with their technical advisors, Telesat of Canada, attended seven days of meetings at SSTL's headquarters in Guildford as part of the PDR.

NigeriaSat-2 is scheduled for launch in 2009.
