The evolution of scientific and technical mapping during the last decade has been spectacular. Mapping has made a lot of progress through its new methods as well as its devices and various and abundant data.

Mapping also takes its performance from scientific and technical progress. It also takes advantage from the benefits of computing, optical and space technologies and methodological quantitative analysis

Likewise, the local geographical space becomes more and more a subject of preoccupation, because it contains many specific and complex dynamics, interactions and interrelations.

The goal of this paper is to put into practice the appropriate methodological mapping based on air photos and numerical satellite images and the topographical maps, in order to put into evidence spacial transformations in el Alia area, in Tunisia. This will be done in systemic approach.

In fact, air-photos and old topographical maps constitute a milieu and a territorial memory.

Numerical images satellite at very high resolution brings new insights in spacial information and a new approach to the complexity of the geographical space.
