GIS can be an effective tool for sustainable tourism development by helping decision makers evaluate environmental impacts, identify potential conflicts, and model relationships between tourism and other sectors. GIS allows tourism data to be integrated and analyzed spatially, helping with resource mapping, impact assessment, and tourism planning. Some benefits of GIS for tourism include cost savings through efficiency, improved decision making considering location factors, better communication of geographic information, and managing tourism development geographically. While challenges remain, GIS has been successfully used in tourism applications like mapping attractions and building interactive online maps.
