One of the earliest applications of GIS in tourism planning is discussed by [4] in the US Virgin Islands. Using three models he defined conservation areas, ecological research areas, and areas of residential and recreational development while, a fourth model was used for conflict resolution among competing uses. [5] used multi-criteria evaluation method and GIS as a practical instrument to evaluate the suitability of Guilan Province coast of Iran for sustainable tourism destinations using Analytical Hierarchy Process (AHP) and GIS. Similarly, [6] demonstrated the application of GIS in the identification of areas suitable for ecotourism in Northern Ontario, Canada. Reference [7] used GIS to locate areas suitable for tourism development at Lombok Island in Indonesia. [8] developed a GIS based decision support system for sound spatial planning for tourism in Mauritius. [9] used GIS and AHP to identify and prioritize potential ecotourism sites in Surat Thani Province, Thailand.
