  The utilization of web mapping becomes increasingly important in the domain
of cartography. Users want access to spatial data on the web specific to their
needs. For this reason, different approaches were appeared for generating
on-the-fly the maps demanded by users, but those not suffice for guide a
flexible and efficient process. Thus, new approach must be developed for
improving this process according to the user needs. This work focuses on
defining a new strategy which improves on-the-fly map generalization process
and resolves the spatial conflicts. This approach uses the multiple
representation and cartographic generalization. The map generalization process
is based on the implementation of multi- agent system where each agent was
equipped with a genetic patrimony.
