On July 6, 2011 the International Olympic committee chose the city of Pyeongchang to host 2018 Winter Olympics after three times of city's trial. But the Environmental Organizations are warning that Mt. Gariwang where the downhill competitions are scheduled to be held needs to be replaced because of natural resources protection area. 5 alternative places over an altitude of 800 meters using GIS among Pyeongchang and Jungsun areas were discussed at the Uiyoung Forum. We studied those 5 substitutes places to meet the requirements of downhill stadium of International Ski Federation by producing longitudinal profile map using DAS program. First, Mt. Sangwon is inappropriate for the downhill stadium because the easy slope of lower section of the mountain for the beginner's level is too long and doesn't fit the difference of altitude and the level of difficulty. Second, Mt. Baeksuk is also inappropriate for the downhill because over 2 Km of lower section of the mountain is pretty easy and doesn't fit the difference of altitude and the level of difficulty. Third, Mt parkji is inappropriate even though the slope of middle section of mountain is pretty steep, the 1,600 meters of upper and lower section of the mountain has easy slope. Fourth, Mt. Doowi is inappropriate for the downhill because over 2Km of middle and lower section of the mountain shows easy slope of 12% and doesn't fit the difference of altitude and the level of difficulty. Fifth, Mt. Baekduk is also inappropriate because over 2Km of middle and lower section of the mountain has easy slope along the valley after passing steep slope of upper part of the mountain and doesn't fit the difference of altitude and the level of difficulty.
