made available damage analysis maps based on Ikonos satellite
imagery (1 m resolution).
The products (SERTIT processing) delivered to the Iranian
authorities consist of estimated damages zonation maps (in fact
change detection) over the Bam city from satellites data and
also damages zonation maps correlated with land use:
2.2 Floods
A major flood occurred over the south of France December
4, 2003 (Rhône river), as an example the town of Arles
(northbound) was over flooded for a number of days and rescue
teams from France and Germany had to pump out the water for
several weeks. Six people were killed and over 15,000 were
forced to leave their homes.
Satellite imagery was again useful for the CPAs and once more
[konos data were provided by European Space Imaging to help
the rescue operation in addition of Spot 4 and 5 and Radarsat.
Value added products (CNES and SERTIT processing) included
flood extension maps, impact maps on a very large area (130 x
160 Km) and also local maps on a number of small towns
affected by this disaster. For this purpose administrative
boundaries were merged together with land use. The example
hereunder clearly demonstrates the flood recess between two
dates: December 6 and 9, 2003 using two Radarsat images and
the detailed land use from a Spot 5 recent archive.

Unprecedented floods "the worst since the foundation of the
town of Santa Fe in 1573" affected the whole province and
nearby areas in central Argentina, April 30, 2003, causing
evacuation of 60,000 inhabitants. The Water Institute fears that
the situation would last for weeks due to high phreatic levels
and abnormal precipitation.
The Charter was therefore triggered by the Argentinean Federal
Emergency System, Radarsat and Spot satellites were tasked
and the hereunder flood map of the town of Santa Fe was
produced together with CONAE and the National Water
Institute, in order to help the local civil protection authority:

2.3 Forest fires
The extent of the burned area and the potential danger for the
nearby population justified triggering of the Charter July 19
and 25, 2003 (Var district in France).
The local French CPA required as soon as possible a map of the
burned area with a maximum resolution due to threatened
houses close to the fire. They were expected new fires in the
vicinity. The Spot tasking was concentrated to Spot 5 because
of its high resolution (2.5 m) and the information reached the
fire fighters only 76 h after the request. However as the threat
was continuing, the next request was timely with Spot 5 track
over the area and CNES processed imagery was provided 21h
after the request and only 5 h after the Spot 5 satellite pass.
User feedback for this type of disaster allows us to indicate:
- the need of high resolution (2.5 m is acceptable),
- the need of quick delivery of even raw data as the
identification of burned areas is easy,
- the need of high resolution archives allowing identification
of recent constructions.
The extent of the burned area in the Maures region (over
20,000 ha were destroyed) from Sainte Maxime (along the
coast) to Vidauban (north west on the image) is clearly visible:
2.4 Oil spill
When the « Prestige » tanker oil spill occurred close to the
Galicia coast (Spain), mid November 2002, the Charter was
activated by both the European Commission, civil protection
and environmental accidents unit and the French CPA. The
Prestige started leaking fuel, then the tanker was pulled out far
from the shore and finally sunk after splitting in half.
