This chapter describes and discusses a work aiming to contribute to how dynamic sustainable development indicators may be spatially represented in a generic spatial-integrated socioeconomic model (SISM). It means that, at a socioeconomic level, the resulting SISM should be capable of supporting applications modelled at different territorial scales and, at a spatial level, the SISM should be capable (a) of spatially representing the temporal evolution of the indicators by itself and (b) of exporting, at any time during a SISM simulation, the temporal evolution of the spatial state of the model as a (new) map exploitable in a GIS tool. The proposal from this chapter is to design a generic object-based SISM resulting from a combination of a multi-agent model and an object-based version of a system dynamics model so that all selected indicators can be spatialised via shaped objects independently of the territory study and the modelling approach.
