| Assessing the sustainability of a tourist destination becomes more and more complex, because the involved actors must cooperate with the economic, social and environmental requirements that represent the pillars of sustainable development. Geographic Information Systems (GIS) can be seen as a toolbox of techniques and technologies widely applied to achieving sustainable tourism development. Spatial data can be used to track, control the state of sustainability and aid in decision making. Assessment is increasingly important in tourism development, based upon GIS that can play an important role in auditing environmental, economic and social conditions. Systematic evaluation of the environmental impact is often hampered by gaps in information but also in tools for integrating, manipulating, visualizing and analyzing data.GIS seems particularly suitable to this task. This article provides a systematic model evaluation for sustainable tourism. Moreover, a geoportalsoftware is designed towards the use of GIS and its implementation for a case study on sustainable tourism in Morocco at Tangier.
