Geocoder is a library for Ruby developers and a command-line utility
that helps with converting street addresses (U.S. only for now, I'm
afraid) to geographic coordinate pairs, specifically, latitude &
longitude.
The library is useful for developers who want to incorporate geocoding
into their Ruby applications; the command-line utility, `geocode', is
useful for one-offs, shell scripts, and non-Ruby apps.
The library is a wrapper for various geocoding web services. The two
services currently utilized are 1) Yahoo! Maps Geocoding API, and 2) geocoder.us (looking your way, GMaps!).
CLI example:
$ geocode "1600 pennsylvania ave nw washington dc"
Latitude: 38.8987
Longitude: -77.037223
Address: 1600 PENNSYLVANIA AVE NW
City: WASHINGTON
State: DC
ZIP Code: 20502-0001

Thank you! I've been looking for something like this.

I'm working on a port of the perl Geo::Coder libraries, so you can
host the tiger line data locally and not rely on any web
services. Results may differ from yahoo maps but should be identical
to geocoder.us. I know I've been needing something like this, and I
don't like using too many web services.
No ETA yet though.

Will it eventually be able to do the reverse lookup? Lat/Long to street address?

I think Yahoo supports Canada, so would the library with the yahoo option
support Canada?
Thanks,

Hey I just thought I'd mention that I'm half heartedly porting the Perl
Shapefile library. We might end up with a nice little collection of
GIS libraries for ruby after all
.adam
Hm, I don't know of any system, commercial or otherwise, that does
this. Geocoding is a relatively inexact science to begin with (re:
interpolation of street number ala TIGER/Line), I would be surprised
if anyone's doing this reliably. That said, it could be done if you
massively indexed the lat/lng side and had a best guess algorithm that
used a nearest() function or the like. ... To answer your question,
no, no plans to add that functionality to Geocoder.
By the way, I just pushed a 0.1.1 release to Rubyforge: it fixes a
minor issue with the gem, removing the redundant require statement
after require_gem.
Let me know how you fare: I'd like Geocoder to provide the flexibility
to use TIGER/Line "offline" if users want it. Perhaps we can
collaborate.

Perhaps we should start a rubyforge project and work together on this,
as Dominic suggested. Having a nice set of well coded Geo libraries
in ruby would be AWESOME!

For my gf's senior project, she made a device for the blind that
basically did this; you hit a button and it tells you your current
street address (other buttons for nearest landmarks, etc). It's
written in C, but I've been thinking of porting it to ruby just for
fun. The accuracy isn't any better than TIGER/Line's accuracy, but
it's generally usable. Anyhow, it can be done
This appears to be much more flexible
