Africa Data Dissemination Service (ADDS)
WWW site, sponsored as part of the FEWS programme by USAID and EROS, with
data from ARD, NOAA, NASA and the CIA. Provides statistical and map data on
Africa. Data/maps are arranged into both country and theme sections. Data
can be downloaded directly, maps can be viewed online. Data holdings include
satellite data (Normalized Difference Vegetation Index (AVHRR NDVI)) at both
regional and national aggregations), administrative boundary files (AGMAN
format), agricultural statistics (AGMAN Format), precipitation (Rainman
format), prices (PRICEMAN format). Maps available vary from country to
country, but include: country maps (usually a general reference map, an
administrative boundaries map (in various levels of detail)),
agricultural/cropping maps, hydrology maps. The AGMAN (agricultural) RAINMAN
(rainfall) and PRICEMAN (prices) data and software can be downloaded from
the WWW.

DMCii pioneers new framework for satellite imaging quality control
Remote sensing solution provider DMCii’sChief Scientist, Dr Steve Mackin, has pioneered a new approach forderiving quality control indicators from Disaster MonitoringConstellation data. The new framework, which is being implemented byDMCii, holds great potential for quality control and consistency inmulti-source imaging projects such as the European Global Monitoringfor Environment and Security (GMES).
Dr Mackin commented:“This has never been done before and its application holds greatpotential for projects where imaging is sourced from multiple providersand satellites. As a GMES contributor, DMCii has begun implementingthis new quality control framework within the Disaster MonitoringConstellation to validate it for wider use.”
The European SpaceAgency (ESA) has expressed interest in the techniques that Dr Mackinpresented in his role as one of the UK’s representatives in the WorkingGroup for Constellation Calibration on the Committee on EarthObservation Satellites (CEOS). The first dedicated GMES satellites,Sentinel 2 and Sentinel 3, will demonstrate (at least in part) the newframework as a quality control measure for GMES.
From researchconducted with the National Physics Laboratory it was clear that makingextra quality information available to describe imaging products wouldbe of significant benefit to imaging experts. The new frameworkprovides a clearer quality statement with defined error budgets at eachstage and hence identifies low quality data before it can be issued.The traceability of data is also improved, enabling the rapididentification of the processing area at fault.
Dr Mackin statesthat the proposed methodology holds many benefits for imaging users:“It makes sense for any customer to request standardized qualitycontrol information from imaging suppliers. Only then can you be sureof the quality of your end product and its fitness for purpose. It alsoallows users to compare data across image providers in a fast andsimple manner and determine who meets the user’s requirements at thelowest cost – hence saving time and money for the end-user”.
TheDisaster Monitoring Constellation (DMC) is a unique cooperation betweenpartners that own satellites and share their data. DMCii coordinatesthe constellation to provide high quality commercial imaging servicesand rapid disaster monitoring programmes. The DMC’s imaging capacity isset to grow to more than 10 million sq km per day by the end of 2008with the addition of new satellites, UK-DMC2 and Deimos-1, which sharea 20metre 600km swath imaging capability. The UK-DMC2 satellite willalso offer a direct downlink service to X-band groundstations.
Lastyear, DMCii imaged 38 European countries for GMES in the 6 monthsbetween April and October 2007 as a GMES contributing mission. DMCiidelivered precisely positioned data in each national map projection.This was the first time that the whole of Europe had been successfullyimaged at high resolution in a single year.
The GlobalMonitoring for Environment and Security (GMES) programme (recently renamed Kopernikus) is led by theEuropean Commission with the aim of delivering environment and securityservices. It is the European response to the ever-increasing demands ofeffective environmental policies. GMES is the European contribution tothe Global Earth Observation System of Systems (GEOSS).

EUMETSTAT: Access to data
EUMETSAT provides an extensive range of high-quality satellite data, products and services. The primary services of EUMETSAT are those associated with the data from Meteosat first and second generation satellite series. These data, products and services are made available via EUMETCast, the Meteosat satellites themselves (direct dissemination), the Global Telecommunication System (GTS) and FTP over the Internet.
In addition, EUMETSAT plays an important role in the retransmission of a variety of other satellite data, meteorological products and environmental data generated by our partners and a growing network of external data providers.

GeoEye-1 Satellite successfully launched
Satellite Imaging Corporation acquires and processes imagery from the
groundbreaking GeoEye-1 satellite sensor. The satellite sensor launched
on September 6, 2008.
The GeoEye-1 Satellite sensor was developed by GeoEye and features
the most sophisticated technology ever used in a commercial remote
sensing system.
GeoEye-1 is capable of acquiring image data at 0.41 meter panchromatic (B&W) and 1.65 meter multispectral
resolution. It also features a revisit time of less than three days, as
well as the ability to locate an object within just three meters of its
physical location.
This newly developed sensor is
optimized for large projects, as it can collect over 350,000 square
kilometers of pan-sharpened multispectral satellite imagery every day.

Satellite data-sharing to benefit poorer nations
A new data-pooling system will make data from satellites run by China, Europe and the United States available for a fee of US$1,500: This new satellite-based information system will allow poorer nations to gain cheap access to crop, health and climate data, enabling them to better prepare for natural disasters. Starting next year, the GEONETCast system will give countries access to data gathered by satellites and weather stations run largely by the world's richer nations. To receive the data, users must buy a receiver and a US$1,500 licence fee. The system combines satellites operated by China, Europe and the United States, and was demonstrated this week (28 November) at a conference of the Group on Earth Observations in Bonn, Germany. The satellite data could be used by officials trying to contain forest fires, who could use near real-time data on wind speed, wind direction and surface temperature to forecast the course of the fire. Data on soil moisture, rain and vegetation cover could help officials forecast droughts, enabling farmers and governments to take preventive steps. China's participation in the project gives it access to a more comprehensive global data set and the chance to improve its satellite technology, said Zhu Xiaoxiang, a senior researcher at the National Satellite Meteorological Centre. The Group on Earth Observations includes 66 countries, the European Union and 43 international organisations. The group's GEONETCast project is organised by China, the United States, the World Meteorological Organization and EUMETSAT, which operates European weather satellites.
