What Ruby / Rails geocoding library is compatible with (can fetch data from)开发者_如何学运维:

• latest Yahoo PlaceFinder api

• latest Google V3 API

• Bing maps API

Please also comment on the compatibility with Rails 3 and Ruby 1.9

Ruby Geocoder supports Google V3 (the default), and can be configured to use Yahoo Placefinder or Bing. It's also Rails 3 and Ruby 1.9 compatible. It appears to have broader support and be more regularly maintained than geokit.

Comment from site about compability:

Geokit is Ruby 1.9.1 compatible!

I don't know about geokit-rails and rails 3, but you need only geokit gem for geocoding.
