## How to
Access interactive shell of the PostgreSQL container.
This project is using shapefiles from https://business.juso.go.kr/ as an example.
For this example, we only run ctprvn, sig, and emd with the following command.
First, place "구형의 도역 XX월 전체.zip" in the shapefiles/ directory.
And then run the following command.
```shell
$ make create # Create shapefiles under migrations/ and run the migrations
```
## Check the result
```shell
$ make shell
```
```shell
$ psql -U postgres
```
```sql
SELECT gid,
emd_cd,
emd_eng_nm,
emd_kor_nm,
ST_AsGeoJSON(geom) AS geom -- Exclude this colum if not needed
FROM tl_scco_emd;
SELECT gid,
sig_cd,
sig_eng_nm,
sig_kor_nm,
ST_AsGeoJSON(geom) AS geom -- Exclude this colum if not needed
FROM tl_scco_sig;
SELECT gid,
ctprvn_cd,
ctp_eng_nm,
ctp_kor_nm,
ST_AsGeoJSON(geom) AS geom -- Exclude this colum if not needed
FROM tl_scco_ctprvn;
```
Copy the geojson column value and paste it in https://geojson.io/, and you will see a geometry of
some place in Korea.
Or you can use the following query to see an intersection of two geometries.
```sql
select *
from tl_scco_sig
where ST_Intersects(geom, ST_GeomFromText('POINT(126.9858 37.5600)', 4326));
```
## Destroy the database
```shell
$ make destroy # Cleans up shapefiles/ and drops the database
$ make migration:clean # Cleans up migrations/. Don't run if you want to keep the migrations
```
## Tips
### Do not use Docker PostGIS alpine image
If you use the alpine image, you will get the following error.
```shell
$ shp2pgsql -s 5186 -W cp949 /shapefiles/11000/TL_SCCO_SIG.shp
Error loading shared library libintl.so.8: No such file or directory (needed by /usr/local/bin/shp2pgsql)
Error relocating /usr/local/bin/shp2pgsql: libintl_bindtextdomain: symbol not found
Error relocating /usr/local/bin/shp2pgsql: libintl_textdomain: symbol not found
Error relocating /usr/local/bin/shp2pgsql: libintl_gettext: symbol not found
```
However, if you use postgis instead of postgis-alpine, you will get this error instead.
```shell
# shp2pgsql
bash: shp2pgsql: command not found
```
You can refer to
this [issue](https://gis.stackexchange.com/questions/384381/shp2pgsql-available-in-postgis13-3-1-alpine-but-no-in-postgis13-3-1-docker-ima).
It's already fixed in this repository; check out the Dockerfile.
