QGIS practice with NGII(National Geographic Information Institute) data of South Korea

Basic setup sequence

1. Install QGIS for OS platform

• https://www.qgis.org/ko/site/forusers/download.html

2. Install QGIS plugin for South Korea (TMS for Korea)

• https://plugins.qgis.org/plugins/tmsforkorea/

3. Download Gyeonggi GIS data in NGII openmarket (Required Sign Up)

• address : http://data.nsdi.go.kr/dataset/12771

• road : http://data.nsdi.go.kr/dataset/12665

• building : http://data.nsdi.go.kr/dataset/12623

• contour line : http://data.nsdi.go.kr/dataset/20180927ds0069

4. Launch QGIS

5. Import Kakao map to layers

• Menu > Web > TMS for Korea > Kakao Maps > Kakao Hybrid

6. Import Gyeonggi address data to layers

• Drag shp file to QGIS (e.g. LSMD_CONT_LDREG_41_202205.shp)

7. Import Gyeonggi road data to layers

• Drag shp file to QGIS (e.g. LSMD_CONT_UQ161_41_202205.shp)

8. Import Gyeonggi building data to layers

• Drag shp file to QGIS (e.g. F_FAC_BUILDING_41_202205.shp)

9. Import Gyeonggi contour line data to layers

• Drag shp file to QGIS (e.g. Z_NGII_N3L_F0010000_A.shp,Z_NGII_N3L_F0010000_B.shp,Z_NGII_N3L_F0010000_D.shp,Z_NGII_N3L_F0010000_E.shp,Z_NGII_N3L_F0010000_F.shp,Z_NGII_N3L_F0010000_G.shp,Z_NGII_N3L_F0010000_I.shp,Z_NGII_N3L_F0010000_J.shp,Z_NGII_N3L_F0010000_K.shp)
