Overview

Through is a small geolocation web API. You can use it to:

• Look up the location of an IP address
• Find out the time zone for a location
• Get responses in JSON
• Centralise your geographical data so each of your apps don’t need to store it

I didn’t want to reproduce the same functionality across my web apps, so I thought an API would be a good solution.

Installation

1. Install libgeoip (sudo port install libgeoip)
2. Install the ruby binding (sudo gem install geoip_city)
3. Get the data: (curl -O http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz)
4. Get some time zone mapping data (curl http://www.maxmind.com/timezone.txt > data/timezone.txt)
