The operator would turn over to the Assessment
Mode if the alarm was verified and the slick was judged not to be harmless.
The Assessment Mode could also be started before a possible aircraft verification
in order to determine if resources should be spent on aircraft verification.
This mode allows the operator to place the oil slick in correct geographic
context. Various map overlays are shown on top of the image, e.g. maps
showing fishing areas, sea farms, recreational areas and environmental
fragile areas. The operator may also add wind information in order to better
determine the possible development of the situation. The module includes
oil slick development simulators. There are two simulators. One is based
on an empirical relationship between the oil slick, wind and sea currents.
The other is a comprehensive physical model. The result of the modelling
is a map showing the probable oil slick trajectory in the area covered.
If the situation is threatening commercial or environmental resources,
the operator may choose to switch to the next mode: Operations.
Assessment viewer and two windows. The viewer shows the predicted
trajectory of the oil slick the next eight hours. Commercial beaches in
blue, natural reserves inside pink polygones, important fishing resources
inside yellow polygone. Hence, the oil slick (in red) will probably
reach a commercial beach in eight hours. Left window shows information
about the SAR image, meteorological data and simulation parameters. Right
window is used to enter information in order to generate an alarm report
automatically.
