Data.go.kr is the public data portal of the Republic of Korea, one of the most prolific national open data programs in the world by number of datasets and open APIs. It aggregates data from central ministries, local governments, and public institutions.
Spatial coverage includes administrative boundaries, addresses, land use, transport, and environmental data, much of it under the Korea Open Government Licence. The portal's strong emphasis on open APIs makes it well suited to programmatic and application use.
