Geographical Information Systems are also excellent tools for analysis. They allow to combine the analysis of "non-spatial" information (as we can do in a common database) with the analysis of the characteristics of distribution of the phenomena.
N.A.D.A.R. led numerous studies of spatial analysis of various types including studying dispersal patterns, analyzing transport fluxes on a communication network, determining the spatial variance of demographic variables, etc.
A variant of the spatial analysis is the elaboration of multi-criteria models. N.A.D.A.R. developed a long expertise in this domain, mostly in problems of optimal location.
