# Creation steps
1. Upload the allCountries and alternateNames tables
2. Generate the `global_cities_points_limited` and `global_cities_alternates_limited` tables
3. Run the `sql/build_data_table.sql` script to build the `global_cities_points_limited` table
**Note**: The generation script for `global_cities_alternates_limited` is missing.
# Data Sources
* Geonames free gazzeter data. `allCountries.zip` file available [here](http://download.geonames.org/export/dump/allCountries.zip). `alternateNames.zip` file available [here](http://download.geonames.org/export/dump/alternateNames.zip).
# Testing
In order to test the data and the functions created under the script avaialble in this folder, you will need to run `bash test.sh` from `test/data` and `test/functions`.
# Historic:
* [23/06/2015]:
* `README.md` file generated
* Added structure for `/test`
