There are two main approaches for incorporating spatial objectives into the planning process, the exogenous and the endogenous approaches:

In the exogenous approach, no spatial information is used into the optimisation, but predetermined spatial constraints area taken into account. This exogenous approach could be useful for example when set-aside areas (e.g. key habitats) are decided in advance<ref>BETTINGER, P. et Y.-H.
