How can we map land use to model ecological networks? General methodology and case study in the Île-de-France

Abstract

This paper aims to propose a methodological framework for land cover mapping, particularly for its use in modelling ecological networks. The quality of the modelling results is highly dependent on this step carried out upstream, which is however rarely detailed in the bibliography. We therefore propose to explain the approach and the different steps that lead to the realization of a precise mapping of the land use of a territory using the different GIS databases already available. We then we present a case study for the Île-de-France region. The objective of this article is to provide a basic, operational and essential decision-making tool for space managers or researchers for a better understanding of the territory and the issues related to ecological networks in France.
