Effective development by relief suitability and transport infrastructure of the Obârșia Lotrului ski area

Relief and climatic conditions represent two defining elements for the development of a ski area in a mountain area. The study proposes an evaluation of parameters of particle morphology and morphographic relief, in order to identify the most suitable areas. The analysis of the slope and exposure of the hips, to which we can add the geology and the land cover, needs a high accuracy GIS project. The technical longitudinal profiles of the proposed slopes, represents a good tool for determining the slopes degrees of difficulty. At the same time, the study proposes the validation for the profitability rates of the ski area. The methodology focuses on two main stages. In the first stage, based on the GIS techniques, were identified the sustainability areas for the ski slopes, while in the second stage was conducted if the ski lift infrastructure is enough developed to serve the proposed ski domain.
