- gooru, on 10/12/2007, -0/+12Not to troll (OK, I guess I kind of am), but the Google Maps API documentation is really quite good for understanding geocoding:
http://www.google.com/apis/maps/documentation/#Geocoding_Examples - Chewie67, on 10/12/2007, -0/+10Nice! This is a feature they've been needing for a while now.
- rgov, on 10/12/2007, -0/+6This wasn't really "quietly added." They announced it on their blog on the 12th: http://googleblog.blogspot.com/2006/06/happy-birthday-google-earth.html
- Chewie67, on 10/12/2007, -0/+4That's an impressive chart, but based on my tests, Google was more accurate than Ontok. Neither got it "just right", but Google was a lot closer.
- datagod, on 10/12/2007, -0/+4I am waiting for them to convert IP addresses to Physical Addresses.
I want to put popup pins on a map showing where various visitors to my website are coming from. - Chewie67, on 10/12/2007, -0/+3Good examples. The accuracy isn't fantastic, however. The two examples I tried put the pin on the map about a thousand yards away from the actual location of the address. That's acceptable for some applications, but not all.
- b0nj0m0n, on 10/12/2007, -0/+3This is a powerful step. Computers in vehicles are becoming more common, and although it won't supplant the GPS navigators, it will give you an informational hook. You carry a cell phone with GPS, I can find you on Google Maps, we have ourselves a use case.
It's a bit stunning that it took this long. Isn't it a relatively simple upgrade? - AhmedF, on 10/12/2007, -0/+2Need an independent comparison ...
- f209, on 10/12/2007, -0/+2this has been available from yahoo for quite some time... Now the real question is...who will be the first to offer free REVERSE GeoCoding.
- AhmedF, on 10/12/2007, -0/+2There is a $10k version?
- inactive, on 10/12/2007, -0/+1Yep. Works been looking at it for a while now. There's a slight lack of details as to exactly what the benefits are at this point.
- fortezza, on 10/12/2007, -0/+1I like map quest.
Yeah, I like them, too.
Google Maps is the best.
Yeah, true.
Double True! - andreit, on 10/12/2007, -0/+1Finally, I've been waiting for this one for sometime now. Geocoding service would be an awesome addition of Advanced Flash Components (http://www.afcomponents.com) Google Flash Map Component (http://www.afcomponents.com/map_google/).
- cbonanno, on 10/12/2007, -1/+2now all they need is traffic and weather and they are set!
- hchaudh1, on 10/12/2007, -1/+2This is a great feature. Also Sun and Google are working to get this stuff integrated with Aerith. Geocoded trips, with pictures and music, great!
http://swinglabs.org/index.jsp - mikepurvis, on 10/12/2007, -0/+1They're not going to put the best data in the free API, of course. That's what the $10k per year version is all about. :)
- vh1`, on 10/12/2007, -0/+1does this only work with addresses?
as others have said, it's a couple of really quick and easy regexps to pull the data, and you can use address, business, or keywords
ie (I hope digg doesn't garble the links):

http://vh1.railsplayground.com/hotspots/api/search/?query=coffee - jpristel, on 10/10/2007, -0/+1http://www.freereversegeo.com just updated their site and now it contains code examples for their reverse geocoding api to use with google maps...
- Bradl3y, on 10/12/2007, -0/+1Unless you make a lot of requests per day, because google limites the amount you can make (to about 1.6 requests per second avg)
- bugninja, on 10/12/2007, -2/+2This changes everything! Watch as Google Maps EXPLODES now!
- programmingjeff, on 10/12/2007, -1/+1This is a feature that's long been requested.
Darn, I just created an automatic Google Maps geocoder about 1.5 weeks ago in PHP. Guess I don't need it anymore... - jcostom, on 10/12/2007, -1/+1Wonderful feature addition. Only problem I've got is that Google seems to think that our current house is about 2 blocks away from where it actually is. We're (hopefully) moving next month, and thankfully, Google DOES know where our new house actually sits. Presumably their geocoding data is a bit off for lots of addresses...

http://mapperz.blogspot.com/ - c4mden, on 10/12/2007, -0/+0I'm certain that Google didn't wait this long to roll out a geocoder for purely technical reasons. Probably has more to do with licensing. Google doesn't own any of the street data, they purchase it from Navteq and possibly others. Those companies do a lot of work compiling geo-street data, and usually get compensated by people paying them for services such as geocoding.
When sites like Google, Yahoo, etc roll out free geocoders, that must throw quite a wrench in the business plan for the data providers. I assume Google just agreed to pay the company more money in exchange for being able to provide it to their users for free.
This same business-model issue is probably why Google doesn't have an API for Google Local yet. Most places that collect yellow-pages type business listings charge people for access to the information. I'm sure Google is paying them a good chunk of change, and the companies don't want Google to just turn around and release that same data for free. Now sure how Yahoo has gotten around this issue with their local API. - jpristel, on 10/11/2007, -0/+0http://www.freereversegeo.com
- hmaurich, on 10/11/2007, -0/+0Thanks for this story! On http://www.geokodierung.net you find some interesting php-scripts and exact geodatas for your adress for free.
- Bradl3y, on 10/12/2007, -0/+0I am trying to implement the "Retreiving placemark details" code, but it doesnt seem to be working...
var streetAddress = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.Thoroughfare.ThoroughfareName;
var city = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.SubAdministrativeAreaName;
var state = place.AddressDetails.Country.AdministrativeArea.AdministrativeAreaName;
var zip = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.PostalCode.PostalCodeNumber;
// Add address information to marker
marker.openInfoWindowHtml(restaurant ''
streetAddress ''
city ', ' state ' ' zip);
it seems only the var city one will actually pull data, and it pulls the county name not the city name, it seems to have problems when trying to retreive anything in the locality, infact if those lines are present requesting that data, anything after that line of code will not function, anyone shed some light on this? anyone got this working? - rektide, on 10/12/2007, -5/+2Whine whine whine. It was liek a 25 character regex to pull the lat & lng out of maps.google.com/maps?q=
My Ontok/Yahoo/GoogleMaps geocoder was like 60 lines and did everything asychronously. Not a biggie.
And yes, free services have been available from Yahoo and Ontok for a while. Ontok has a good comparison, which I've found to be reasonably representative.
http://www.ontok.com/geocode/compare - strictnein, on 10/12/2007, -7/+3yahoo's had this for quite some time, I believe. But since it's google, I guess we're all going to splooge all over the place
- BostonMark, on 10/12/2007, -4/+0Sweet...
Now I'm just waiting for the resolutions of Google Maps to be implemented in their API service. - burnt1ce85, on 10/12/2007, -6/+1ignore this.
- right75, on 10/12/2007, -7/+0Indeed. It seems pretty weak that they haven't included that until now.
Digg me. - jghassell, on 10/12/2007, -9/+0I am awed by your geographic knowledge.
- SIDSI, on 10/12/2007, -9/+0...---...
