This chapter illustrates the implementation of a conventional methodology in landscape ecology. The method is based on an existing landscape representation, i.e. a land cover description of the landscape which consists of the following steps: computation of a set of features and use of the features as explanatory variables in a descriptive model built on the observed biodiversity. The chapter shows the feasibility of the analysis in landscape ecology by combining several free tools interfaced with GIS software: the remote sensing tool, Orfeo Toolbox; the landscape descriptors calculation tool, Landscape ecology statistics (LecoS); and the statistical modeling tool, R, and its development interface, R Studio. The proposed three‐step method is adapted to the free and open‐access software, Quantum GIS (QGIS 2.18 Windows), so that a user, without large expertise in remote sensing and geomatics, can use it without signing up for use of software licenses.
