For 25 years now the territorial intelligence method Catalysis offers a multidimensional and multisectorial approach to territory. It integrates quantitative analysis, qualitative and spatial methods to co-construct tools available to actors in sustainable development. It is an ambitious way of thinking because of the extremely rapid evolution of information and communication technology and, consequently, of these methods. We passed successively to the idea of a "Catalyse toolkit" that put together tools on a personal computer in the early 2000s, to the concept of "territorial intelligence community systems" at the end of the European program caENTI (2006-2009). SCIT is a socio-technical system that articulates an online integrated technological platform and a partnership of actors cooperating within a joint project, by equating the actors’ network to a users’ network. It is designed as an information system meeting the collaborative uses of the actors. CaENTI had produced a first set of methodological specifications and committed computer modelling of SCIT. The International Cooperation Network “International Network of Territorial Intelligence”, GDRI INTI, continued this research as part of the axis "territorial observation."
