# Deprecated ADM1 geocoder
## Source table:
- Natural Earth Data admin1 states provinces: http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_admin_1_states_provinces.zip which can be replaced by the version without large lakes: http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_admin_1_states_provinces_lakes.zip
## Tables:
- global_province_polygons
## Generation steps:
1. Upload Natural Earth Data admin1 states provinces
2. Rename `adm0_a3` by `iso3`, add columns `frequency` [number] (To calculate frequency, I simply counted the number of users we had signed up in each country. Countries with more users, we favor higher in the geocoder :)) and `synonyms` [string[]]
3. In order to fill the `synonyms` column, you can run the following query:
`UPDATE tablename SET synonyms = Array[lower(woe_name), lower(name), lower(gns_name), lower(gn_name), lower(gn_a1_code), lower(code_hasc), lower(adm1_code), lower(adm1_cod_1), lower(postal)]`
4. Rename table to `global_province_polygons`

# Known issues
* `admin1_decoder` table which is meant to be depreacted is being used in other geocoders, as namedplaces
* All the information in this README.md doesn't contain the actual status of the CartoDB geocoder, which is using the table `global_province_polygons` but not the ones documented above.
* All the information in this README.md doesn't contain the actual status of the CartoDB geocoder, which is using the table `global_province_polygons` documented in the deprecated ADM1 geocoder section.
