1 CONTRIBUTION TO THE SETTING UP OF A GEOGRAPHICAL INFORMATION SYSTEM FOR THE LOCAL MANAGEMENT

What has been noticed at the time of these last years, that the power of domination from all over the world pass inevitably by the restraint of the technology of information. Today, we are too full of us even because of the thick volume of data (therefore of information) that we arrange; but don't forget that the man won't be able to dominate them that if he knows how to manage them, and in particular those relative to his space. To fill this hiatus Algeria tempts since some years to apply this technology of the geographical information at the level local. Researchers and students are invited to actually contribute to the stake of this attention. The survey that confided, enrolls in a work of span and that I will clarify under the term of "Contribution to the setting up of a GIS for the local management". It milked to the GIS Communal and the exam of possibilities offered by the use of this important tool. It has for main objective, and in a vision tool of knowledge and understanding of this geographical space, to conceive an analysis and a modelling of data. Let's place us to the basis of such a survey, and let's retail phases to clear to lead it to term. It is necessary to first of all study the problematic of the cartography to the local scale, that asks for a collaboration with the different administrators of the township. Then, the solution of the problematic and the approach adopted to generate a pilot model of realization of a GIS Communal based on the systemic representation of the territory prove to be necessary. In short and to assure the feasibility and the relevance of our conceptual development the last phase articulates to the validation of the methodology proposed on the township of Arzew (North-Western of Algeria). Our subject is not therefore to provide a product, but rather to determine, to specify and t
