Matrices or look-up tables are increasingly popular flexible tools for ecosystem services mapping and assessment. The matrix approach links types land cover to by providing a score service (ES) capacity, supply, use, demand other concepts. Using expert elicitation enables quick integrative ES scoring that can meet general validated assessment at different scales. Nevertheless, guidance is needed on how collect integrate knowledge address some of the biases limits method. This paper aims propose set guidelines produce matrices based knowledge.
