The need to enhance and share generic and original information from different research projects, led to the design of a dedicated geoweb, called NAMO. Its design uses open and free functionalities that demonstrate their flexibility in an agile and iterative approach. It is in particular the development of two dimensions of valorization and positioning in geoweb 2.0 that is highlighted: narrative mapping and systemic modeling. The use of geographic information, in particular in co-construction and open science approaches, can thus be better equipped.
