3.2. Methods
The AHP weights calculated using Microsoft Excel and ArcGIS 9.3 software were used in the suitability map producing process. There were four crucial steps to produce site suitability map for ecotourism and these are: (1) finding suitable factors to be used in the analysis (2) assigning factor priority, weight and class weight (rating) to the parameters involved (3) generating land suitability map of ecotourism and (4) determining ecotourism potential areas. Details of each processing step are shown in Fig. 2
