GEOMATICS APPROACH FOR URBAN EXTENSION MANAGEMENT CAUGHT BETWEEN PLANNING TOOLS AND REALITY ON THE GROUND, CASE OF THE DISTRICT OF BISKRA (ALGERIA)

Abstract

Biskra city, the administrative center of the Biskra region (wilaya), has poor potential in terms of urban space development; and this is strongly linked to the unfavorable characteristics of the soil with specific geographical features (soil collapse) which prohibits the vertical extension and imposes an urban development horizontal. The incoherence between the urban planning of Saharan cities with a proactive urbanism and the spatial dynamics that obeys other socio-economic factors and financial stakes, due in part to the absence of a prospective vision that It is based on the real needs of an urbanizable space over time, and on the other hand with a reliable spatial analysis allowing an objective diagnosis of the urban space. In view of the large number of variables and their spatiotemporal combination, it is necessary to use geomatics techniques for accurate spatial analysis and sustainable planning. This research work integrates with the results obtained by the geomatic approach compared to conventional land use planning and development master plans (P.D.A.U) which are always outdated even before their approval.
