The use of spatial ergonomics in the issue of resilience is based on the assumption that the ability of a territory to recover its basic functions after a disaster depends on its overall performance level already present during normal times to make available its resources (in the broadest sense: services, activities, supplies, communication, etc.). It is thus necessary to model the system of spatial, functional and cost constraints, conditioning, at different spatial and temporal scales, access to the resources of a territory, by its population and its decision-makers (institutions, Companies), in ordinary situations and in a degraded situation. We present here a first exploration on the capacity of the relation "spatial ergonomics / territorial resilience" to produce diagnostic tools to help develop a resilient management. The methodological approach to analyzing and mapping a degree of spatial ergonomics within a territory will be presented through an experimental example on the Strasbourg agglomeration. The aim of the whole approach is to construct renewed and synthetical information useful to design organization and functioning schemes of resilience.
