1. Import the four files attached in the section "Datasources".
|

1. Import the four files attached in the section "Datasources" for Australia (`doc` table), Canada (`gfsa000a11a_e` table), USA (`tl_2013_us_zcta510` table) and France (`codes_postaux` table).
|
||||
|
||||
2. Run `sql/build_data_table.sql`. Notice that table `postal_code_polygons` should exist in advance with columns: `the_geom`, `adm0_a3` and `postal_code`.
