It takes place normally during the final period of activity. It is not the case for ESPON DB project where diffusion of data and maps to other ESPON projects is a prior task since the very beginning of the period of activity (. Map kit tool and database to be delivered and update regularly). Moreover, one of the tasks of the ESPON DB project is to support.
