Objective: The study aims to analyze the accessibility to grocery stores for reveal the level of access to commercial services for residents of Biskra city (an Algerian desert city) and to identify areas that have difficulty obtaining them, using geographical information systems.

Methods: In order to analyze the accessibility to grocery stores, the study used spatial statistical and network analysis tools (Average Nearest Neighbor and Finding Service Area) which are available in a GIS software environment.

The service area polygons were created around the locations of these stores with a maximum distance of 500 meters, were divided in three categories 100, 300, and 500 meters.

Results: the study showed that the distribution pattern of grocery stores is a convergent cluster type, which that can limit the level of access to commercial services.

In addition to that, the residential neighborhoods located on the margins of the city, especially on the southern side, have difficulty obtaining commercial services.

Conclusions: This inequality in access is controlled by several factors, such as proximity to the city center and the main axes.
