Outline: 1.Introduction
2.Fractal Dimension
3.Geographic Information Systems (GIS)
4.Remote Sensing (RS)
5.Case Studies
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.  These methodologies are applied in geology, geography, navigation agronomy climatic economics and social navigation, agronomy, climatic economics and social sciences, forecasting, etc.
 At least 4 methodological approaches to study landscape metrics: 1) numerical analysis, 2) spatial analysis, 3) multiscalar analysis and 4) spatial modeling analysis.

Landscape analysis can be performed on at least at four levels of spatial resolution: individual, patch, mosaic
ti l l ti i di id l t h i and landscape
d l d
(Figure 8.2).
The measurement of distances can be done according a selection of possibilities: 1. from each patch to all the adjacent neighbors of each patch. 2. from a patch to all others of the same group, 3. from each patch to the p
single nearest patch of a different group, 4. from a patch of a specific group to another patch of a specific group (Figure . 8.5 and Table 8.6).

The GIS appears indispensable for most landscape investigations like:
Land use change
Vegetation patterning
Animal distribution across the landscape
Linking remote sensing with topography
Modeling processes across the landscape

2. The Annual Rate of Change
The annual rate of change for forest was calculated with the formula proposed
by Puyravaud (2003):
1
A2 and A1 = the forest cover areas at the end and the beginning, respectively, of
the period being evaluated.
t1 and t2 = the numbers of years spanning on that period.
