This study examined measures to utilize public-open data sources that can induce environmentally friendly development of wind power generation in South Korea. We reviewed the necessary data for on-land wind power and offshore wind power generation and investigated the development process of on-land wind power and offshore wind power in South Korea. This study presented the current status of South Korea's public open data that can be applied to on-land wind power and offshore wind power development, and identified problems and suggested a scheme that can effectively utilize these data. In the case of on-land wind power, compared to offshore wind power, various data are constructed and thus environment-friendly wind power generation can be effectively induced. In the case of offshore wind power, it is necessary to construct a system that manages scattered marine spatial data in an integrated manner.
