Popis: Understanding urbanization and better management of the city implies a historical perspective of its dynamics. Urban extension which today is a major challenge, is materialized by a rapid urbanization of territories in the margins of cities. Its study in a medium sized city (city of Biskra) is an important issue where it requires monitoring and a detailed analysis of accurate and geolocalized informations. Our research is part of an approach which is based on the use of new geomatics techniques for better analyzing the dynamics of urban extensions. In order to spatialize and evaluate this dynamic, we used a series of Landsat satellite images of medium resolution with three different dates TM 1987, TM 2009 and 2014 for SCEA. The comparison of results obtained confirm that the urban area has increased from one year to another and that the city of Biskra has a medium level of urban sprawl.
