دور الاستشعار عن بعد ونظم المعلومات الجغرافية في تتبع المجالات الهامشية بمدينة الجديدة: حالة السكن غير اللائق

الملخص EN

The city of el Jadida has known, during the last two decades, an important spatial expansion, which contributed to the integration of a set of Douars located around the city in its urban space.

these Douars have known, since its annexation, an important extension, which has not been accompanied by important interventions which aim at the control and the framing of this extension.

these areas have undergone a spatial, demographic and economic dynamic, but they suffer at the level of basic facilities (education, health, sanitation, roads ...) and at the economic level (the expansion of the informal sector).in this paper we will try to follow the extension of these areas through previous studies and research, and through the analysis of a series of satellite images (Landsat) of different years using two indices of built-up area (NDBI and DBI) and calculating the speed of this spatial extension.

then, we will use GPS and GIS to locate the economic activities in these areas in summer 2016.

we will try, also, to make a comparison between what was planned when the 2009-2019 plan was developed and what has been achieved until 2019 in order to identify the needs of these areas.
