List of datasets in tidycensuskr.sf
Notes
- The version 0.2.0 offers ADM2 and ADM3-level boundary data for three census years (2010, 2015, and 2020)
- The bundled data are collected from the Statistical Geographic Information Service (SGIS) of the Korean government, which is the official source of administrative boundaries in South Korea.
- The data are provided in the form of
sfobjects in coordinate reference system (CRS) 5179 (Korea Central Belt 2000). - All bundled data are provided under the Korea Open Government License Type 1, which is a permissive license that allows for free use, modification, and distribution of the data. For more information, please refer to the Korea Open Government License. It is largely based on the Creative Commons Attribution License (CC BY).
ADM2: District-level boundaries
- ADM2, which corresponds to the district/town/township level (so called Si/Gun/Gu [시/군/구] in Korean), is the most detailed level of administrative boundaries available in terms of census data.
- Three separate files are provided in
extdatafolder under the package installation path.adm2_sf_2010.rds: ADM2 boundaries for 2010 censusadm2_sf_2015.rds: ADM2 boundaries for 2015 censusadm2_sf_2020.rds: ADM2 boundaries for 2020 census
- Each file contains a single
sfobject with the following columns:adm2_code: ADM2 code (5-digit)geometry: geometry column containing the polygon boundaries of each ADM2 unit
