Methods in landscape ecology
This chapter represents an attempt to describe, using different approaches, the geometrical attributes of landscapes. The argument remains extremely difficult to reduce to a simple presentation due to the pletora of methods used by authors in very different circumstances, as argued by Hargis et al. (1997). This chapter would not be complete with only books devoted specifically to landscape ecology methods (Turner & Gardner 1991; McGarigal &Marks 1995, Gergel & Turner 2002), but the aim is to introduce and orient the reader toward the main quantitative approaches to measuring landscape features. Consequently, it is important to immediately clarify that the study of the landscape requires metrics but also additional tools like Databases, Spatial Statistics, Geographic Information Systems, Remote Sensing Techniques and Global Positioning Systems, that are used in many other circumstances. In fact, these methodologies are applied in geology, geography, navigation, agronomy, climatic economics and social sciences, forecasting, epidemology, etc.
