This article analyzes the impact of the choice and accuracy of input data on the metrology of the objects of Nature, based on the example of the ecosystem services mapping in the Amazonian pioneer fronts. To do so, field and remote sensing data are linked using regressions. These regressions emphasize : 1) the unequal capacity to map ecosystem services ; 2) the need to adapt the methodology to each indicator ; 3) the need to take into account various [...]
