Pierre Trahan

Mr Trahan spent sixteen years in the Canadian Armed Forces and retired with the rank of Major. He has acquired significant experience in project management over the past twenty years.
In addition to his realisations in the industrial and R&D world, he taught Project management and Finance at the former “Collège Militaire Royal de Saint-Jean”.

Edmond Nezry

Edmond NEZRY was born in Toulouse, France, in 1958. He received an formation in aeronautical engineering, and in physics. He obtained the DEA degree in space techniques and the Ph.D. degree in microwave (radar) remote sensing from the University of Toulouse, in 1988 and 1992.
From 1988 to 1992, he was research assistant at the Centre d'Etude Spatiale des Rayonnements (CESR, Toulouse).
From 1992 to 1993, he was a freelance consultant for various organizations, industries, and universities in France, Germany and Italy.
From 1994 to 1996, he was senior scientist at the Joint Research Centre (Ispra, Italy), where he was responsible for the introduction of ERS SAR data into the operational Agricultural Statistics Project (MARS) of the European Union, and charged of the SAR image processing part of the ERS-1 Central African Mosaic project (CAMP Project).

His main research fields concern speckle filtering (cf. Gamma-Gamma MAP speckle filter development), texture analysis and target detection in SAR images, SAR polarimetry, analysis of SAR time-series applied to the monitoring of agriculture and forestry, and complementarity between sensors. His field of interest extends also to the development of passive far detection systems and of control systems.

He has published over 140 technical papers (articles, reports, communications and monographies) on these topics, and acts as a referee for peer-reviewed journals in the field.
He is principal investigator or co-investigator of JERS-1, TRMM, ALOS (Japan), RADARSAT-1 (Canada), and ERS-1, ERS-2, ENVISAT (Europe) research and application projects.
He is a member of the GEOS (Europe), of the Planetary Society (USA), of the Optical Society of America (USA), and Honorary Member of the Research Board of Advisers of the American Biographical Institute (USA) and of the International Biographical Centre (England).

Iwan Supit

Iwan SUPIT was born in Eindhoven, The Netherlands, in 1959. He received the B.Sc. (1982) and the M.Sc. (1984) in Agricultural Engineering from the Agricultural University of Wageningen (The Netherlands). He received the Ph.D. degree from the Agricultural University of Wageningen on January 7, 2000.

From 1984 to 1986, he was research assistant at the Agro-Biological Research Center (AB-DLO) Wageningen, The Netherlands, working in weather generation studies and using simulated weather as input in crop growth simulation models.
From 1986 to 1988, he was an associate expert for the World Meteorological Organization (Geneva, Switzerland), in Niamey, Niger, where he was in charge to produce yield estimates for sorghum, millet and maize for the Sahellian region, in order to predict shortages of the basic food supply.
From 1988 to 1990, he was associate expert to WMO at Quito, Ecuador, where he assisted the staff of the Ecuadorian meteorological service (INAMHI) in database management, phenological research on maize, climatological zonification, and statistical analysis of weather data.
From 1990 to 1991, he was Consultant at the Ecuadorian meteorological service (INAMHI) for the development of software to analyze data from automatic rain gauges.
From 1992 to 1993, he was Consultant for the Food and Agricultural Organization (FAO) in Bangladesh, where, in cooperation with a Bangladeshi computer consultancy firm, he designed, tested and further developed a "least cost routing" software. This software calculates, for every silo, the replenishment quantity of rice and wheat. Further it calculates the least cost to transport this quantity from the central depots to the silos, taking different modes of transport into consideration. This computer program is installed in the Ministry of Food.
In 1993, he was Consultant for the World Meteorological Organization (WMO), Geneva, Switzerland. In cooperation with the Institute of Remote Sensing Applications, Ispra, Italy, he developed a statistical model to estimate daily values of global radiation. This model forms part of a system which is used to estimate the yields of different crops in the European Community.
In 1994, he was Consultant for the Space Application Institute, Joint Research Center for the E.U., Ispra, Italy, where he prepared the system description of the WOFOST crop simulation model as it is used in the Crop Growth Monitoring System.
From 1995 to Jan. 1999, he was a research assitant at the Space Application Institute at Ispra, Italy, where he developed a methodology to use the Crop Growth Monitoring System for making yield and production estimates for various crops on a national level for all the member states of the European Union.

His main specialities are: irrigation and drainage, climatology, agrometeorology, dynamic meteorology, and hydrogeology.

He has published over 30 technical papers (monographies, articles and communications) in these domains.

Francis Yakam-Simen

Francis YAKAM-SIMEN was born in Yaoundé, Cameroon, in 1961. He received the two Master degrees in physics (1987) and in philosophy (1992) from the University of Toulouse (France). He obtained the DEA (Engineering Specialization) degree in space techniques from the University of Toulouse in 1988, and the Ph.D. degree in physics from the Polytechnic National Institute of Toulouse in 1994.

He is a specialist in fluid mechanics, biophysics, image processing and remote sensing applications.
He is also a specialist in epistemology.
Francis Yakam-Simen has published over 70 technical papers (communications, reports, articles and monographies) covering these topics.

He worked in the field of remote sensing at the Laboratoire d'Etudes et de Recherches en Télédétection Spatiale (LERTS, Toulouse) of CNES, the French Space Agency, from 1988 to 1989.
From 1990 to 1995, he worked as an image processing specialist in medical imagery.

He is principal investigator of a research and development project, in the framework of the CAMP (Study of Central Africa by remote sensing) network of the EEC. He is principal investigator of a research and development project (ALOS, Japan).

Francis Zagolski

Francis ZAGOLSKI was born in Mazingarbe, France, in 1965. He received the Master degree in physics from the University of Lille (France) in 1988. He obtained the DEA degree in space techniques and the Ph.D. degree in remote sensing from the University of Toulouse, in 1990 and 1994 respectively.
