Module: Geokit::Geocoders

Defined in:

lib/geokit/geocoders.rb

Overview

Contains a range of geocoders:

### “regular” address geocoders

• Yahoo Geocoder - requires an API key.

• Geocoder.us - may require authentication if performing more than the free request limit.

• Geocoder.ca - for Canada; may require authentication as well.

• Geonames - a free geocoder

### address geocoders that also provide reverse geocoding

• Google Geocoder - requires an API key.

### IP address geocoders

• IP Geocoder - geocodes an IP address using hostip.info’s web service.

• Geoplugin.net – another IP address geocoder

### The Multigeocoder

• Multi Geocoder - provides failover for the physical location geocoders.

Some of these geocoders require configuration. You don’t have to provide it here. See the README.
