Development cannot be thoughtless for the environment and is to create a convenient and comfortable environment; thus, we should not take only economic factors into consideration as if automobiles cannot be valued more than human beings. People should be considered first because they are the ones who live in developed space; therefore, nature and people should be the main issue when development is planned. This study is to organize these environment and development problems and suggest the fundamental application principle of 'conservation first and development afterward' by discovering problems and measures through the environmental simulation of the Ropeway that was one of major issues in the local community. It is based on the simulation by using the Arc GIS program and Jeju local data from metrical maps (1/2500이 of the national geography service. In addition, the scale modification has been conducted with the consideration of the size of buildings and measured data of the GIS maps. we have discussed the current situation and problems of damage to scenery caused by development of the ropeway construction on Mt. Halla that is World Natural Heritage and essential to scenery factors of Jeju. The cause of the problems was created by development based on the economic logic with its methods with less regards for the local environment. therefore, it is also important to create urban landscape that fits for Jeju as the first stage of success to becoming Juju Free International City. It is very encouraging that the provincial office has recently formed teams for urban design to keep and maintain its scenery and landscape that fit for Jeju. However, there are several problems to be solved before the effort to keep Jeju’s scenery and landscape makes steady headway. First, the problem of the overlap of administrative regulations should be solved. Second, there should be the consistency of the administrative performance. Third, the establishment of a objective standard for the creation of urban scenery based on culture. Fourth. a mature sense of citizenship is needed because there is a limit to administrative efforts to keep the urban scenery and landscape.
