Tourism has found a niche for itself as an effective instrument for generating employment, earning revenue and foreign exchange, protecting environment, preserving culture, tradition and heritage, thereby facilitating overall development. Tourism development in hill stations is highly dependent upon the natural scenic beauty of an area. This study is concerned with identification of potential sites towards tourism development using the view shed analysis tool of GIS and fuzzy logic. With a given terrain and a viewing point, the view shed is the area on the ground that is visible from a specified location or locations. The fuzzy logic technology mentioned in this project utilized a collection of membership functions and rules, instead of Boolean logic, to analyse data. The set of rules in the expert system is known as the Rule base or Knowledge base. The aim of the study was to develop a methodology and identify sites of importance promoting tourist activities and to generate new employment opportunities, thereby creating sustainable growth in the area. The study area of the project is the Katteri town, which is located in the Nilgiris district of TamilNadu. The 3D spatial model was obtained using several themes such as roads, rivers, land cover and surface data. The viewpoints were selected based on higher scenic beauty value and accessibility to roads. The selected viewpoints were given as input into the Fuzzy logic system which functions as a knowledge-based analysis tool. Several iterational analyses were done in the fuzzy logic system, with several aspects such as density of trees, the canopy type, the distance of the feature from the viewpoint etc. The best viewpoint was given as output by the fuzzy logic system. A series of 16 photographs in different angles taken at each of the viewpoint were subjected to visual rating and the results of the analysis and visual rating were compared and the best viewpoint in the comparative study was exactly the same. Presently, the scope of this project is restricted to the identification of potential sites for tourism development. This can be further enhanced by developing an interactive database providing a complete list of the public utilities, areas where accommodation facilities can be developed, other places of interest in the area etc. This can prove to be extremely useful for the tourism development and for generating foreign reserves towards the stability of the revenue.
