===Multi-criteria decision analysis===
{{main | Multiple-criteria decision analysis}}
Coupled with GIS, [[multi-criteria decision analysis]] methods support decision-makers in analysing a set of alternative spatial solutions, such as the most likely ecological habitat for restoration, against multiple criteria, such as vegetation cover or roads. MCDA uses decision rules to aggregate the criteria, which allows the alternative solutions to be ranked or prioritised.<ref name="Greene">{{cite journal | last1 = Greene | first1 = R. | last2 = Devillers | first2 = R. | last3 = Luther | first3 = J.E. | last4 = Eddy | first4 = B.G. | title = GIS-based multi-criteria analysis | journal = Geography Compass | year = 2011 | volume = 5/6 | issue = 6 | pages = 412–432 | doi = 10.1111/j.1749-8198.2011.00431.x }}</ref> GIS MCDA may reduce costs and time involved in identifying potential restoration sites.
