The Geographic Information Systems (GIS) Application in the Evaluation of Sanitary Services in the Big Algerian Cities Empirical Study on the City of Annaba

Foued Benghadbane*

The GIS is one of the empirical scientific methods that are applied in many studies related to the infrastructure. Particularly the distribution of services whether in terms of spatial distribution or ways of present and future work. Moreover, it helps to provide a real picture about distribution and the nature of its connection with the residents’ distribution, density, road network and the existing imbalance in these relations.

The present intervention provides an applied study about the GIS upon the sanitary services in the city of Annaba (the fourth Algerian city) to illustrate the reality of the sanitary equipments distribution and to know the deficiencies by determining their adequacy and efficiency in presenting the sanitary services. This is done by mapping maps (Digital ones) in order to clarify the distribution of sanitary equipments according to its ordinal system (hospitals, clinics, treatment rooms). In addition, there are maps for densities’ distribution, road network, the prominent distances between sanitary equipments with certain dimensions by specifying a service area for each category of sanitary services, by which it can be analysed to reach the perception of new sites that are considered for the sanitary equipments. This perception is based on the program of ArcGIS10.3.

Hence, the applied studies of Geographic Information Systems on the sanitary services have unlimited potentials to reach the exact scientific results, so that, it can obtain the necessary information for enhancing and developing that kind of services in the city of Annaba (Algeria).
