ABSTRACT
Several definitions exist for the term 'landscape' covering various realities and related to the sensitivities and modes of perception from space. The concept of landscape generally refers to 'an extent of land presented by nature to an observer', independent of its meaning in painting. In the definitions of the Larousse and Petit Robert dictionaries, emphasis is on the terms: nature, point of observation and extent of terrain. The concept of agrolandscape is based on the assumption that a spatial, but not random, organisation of environmental factors exists. Spatial organisation of a rural environment is related to its utilisation by man, and the human actions are imprinted in the geographic space. In satellite images, at the resolution of a pixel, various objects are acquired with people true dimensions. In temperate zones, forests are quite readily recognised in a satellite image when they are dense enough and the date of acquisition is carefully taken into consideration.
