Distance to Roads and Highways
To keep construction costs down, a fuzzy analysis was performed on distance to roads. It is difficult and highly subjective determining how willing individuals are to drive to a ski resort on a regular basis or as an international traveller. Assuming the ski area will likely be away from main highways and roads, I conducted a fuzzy analysis using a J-shaped monotonically decreasing curve with control points c= 100,000 m (100 km) as the maximum limit and d= 50,000 m (50 km) as the minimum limit for suitability ranges in distances from roads. The roads image was a rasterized already in IDRISI and needed to be reprojected using NAD 1983 UTM10n. They were reclassed and the DISTANCE module was performed followed by the FUZZY module. |
