 Methodology for mapping the coverage of drinking water services in rural areas 
This article aims to propose a methodology to assess the efficiency of drinking water coverage in rural areas. The process is based on the calculation of a score function which resulted in an index that quantifies any deficits in drinking water coverage. The proposed cartographic model is based on a representation by interpolation of the index value obtained using the score function. The Kernel equation was chosen for the representation using a Geographical Information System (GIS). The approach makes it possible to use cartographic modeling by GIS in order to create a territorial diagnosis of the drinking water supply. The Haut-Sassandra region was used as an experimental field. The theoretical representation obtained is validated by our empirical data.
