System design and organization, access to data
The GIS-Dataset
Basically, the GIS-Dataset used for the Fos-Marseille field trials has
been built using data falling under several main themes: natural (biophysical) and human (socio-economic) environment, coastal monitoring
(quality) and management (protection), risk analysis studies (drifting
oil slicks), regulations (uses, constraints), pollution control (strategy)
and response (equipment and teams).
All this information has been geo-referenced and implemented in a
specific GIS application structured around more than ten main themes,
each composed of several theme-based maps, as shown in the following
example:
- main theme: socio-economic environment;
- theme-based maps: sandy beaches, merchant harbours, industrial
settlements, agricultural land use, etc.;
From the GeoPro interface, every map listed in the atlas can be selected
and displayed (fig. 4).
The clients can access various data such as maps, metadata, images,
tables and texts. The system allows the client to perform the following
functions:
- create, add and save new themes;
- create maps by combining several themes;
- annotate a map by drawing on a theme (graffiti);
- print every mapped theme.
Scenario principle
In accordance with the high ecological and economic sensitivity of the
port area and the real risks of pollution, this scenario was based on the
simulation of an accident (fig. 5).
