A situation model to support collaboration and decision-making inside crisis cells, in real time.

Natural and man-made hazards have many unexpected consequences that concern as many heterogeneous services. The GeNePi project offers to support officials in addressing those events: its purpose is to support the collaboration in the field and the decision-making in the crisis cells.To succeed, the GeNePi system needs to be aware of the ongoing crisis developments. For now, its best chance is to benefit from the ever growing number of available data sources. One of its goals is, therefore, to learn how to manage numerous, heterogeneous, more or less reliable data, in order to interpret them, in time, for the officials. The result consists on a situation model in the shape of a common operational picture.This paper describes every stage of modelling from the raw data selection, to the use of the situation model itself.
