With regards to the big agglomerations and especially the cities, the constructed surface has often got an irregular shape, in spite of the efforts of the urbanists to promote more compact shapes. The internal spatial order of the big agglomerations is a matter of the fractal geometry. This article shows the interest of applying the fractal geometry in cities and in networks of communication of the urban zones. Thus, we are going to focus our attention especially on the coarse analysis of the constructions’ shape structure which concern the occupation of the soil surfaces (the fractal of surface such as the carpets of Sierpinski), and to scale permitting the analysis of the agglomerations and cities such like the city of Constantine, Algeria.
