Is there a good updated source for comparing existing Geocoding APIs (i.e. Google, Mapquest) and their features?

I'm really interested in their language support as well. For example, Google has libraries for its Geocoding service in JavaScript, Java, Python, and many more.

I did a simple comparison a year ago showing eleven different geocoding services, free ones as well as pay services, and the results are in a google spreadsheet. I work at SmartyStreets, so you'll see that listed in the first column but not in first place. I tried to make the comparison unbiased so the results are actually useful. I have now opened the comparison chart for editing by anyone. If you can add to it, please do. Keep your edits objective, don't try to spin things.

geocoding comparison chart

The exact location was determined visually by finding the location on googlemaps and dropping a pin there to obtain the lat/lon.

    The exact location was determined visually by finding the location on googlemaps and dropping a pin there to obtain the lat/lon. When I originally did this, I didn't even think of Bing, though I am adding it now. I'm adding more data points now. I actually have a list of all the McDonalds in the United States with confirmed lat/lon if someone wants to help make a more comprehensive chart. – Jeffrey May 31 '13 at 16:39

    Looks like I need to add that. Give me a little time. – Jeffrey Jun 3 '13 at 18:43

    I've added a second sheet to that comparison. The first sheet compares the geocoding precision and the second sheet compares the features and services offered. – Jeffrey Jun 3 '13 at 20:23

    @TomSchober if you will come up with a complete list of what you'd like to see between the services, I'd be happy to fill in the details. – Jeffrey Jun 3 '13 at 20:24

    Jeffery. I think it would be a fun project to build a comparison tool from your McDonald's list, assuming you would still be willing to share that. You can get ahold of me through fredtrotter.com/contact-fred-trotter – ftrotter Dec 26 '14 at 6:12

There is a free REST API at http://matchbox.io. It standardizes the address and returns lat long as well as other information. For example:

http://api.matchbox.io/address/?addr_1=1390%20Market%20St%20%23107%2C%20San%20Francisco%20CA%2094102

  • Thought it appropriate to add that the Quick Guide at the time of this comment states this concerning Rate-Limit: The Address API is free to use for up to 60 requests per minute – Jared Eitnier Dec 31 '15 at 4:13

I don't know of any such comparison, but I would like to point out that Bing has a REST endpoint you could access from any platform.

The Texas A&M Geoservices site has a comparison of the main features of several geocoding systems - http://geoservices.tamu.edu/Services/Geocode/About/GeocoderList.aspx. We try to keep it as up to date as possible.

  • I realize this is an old post but the services on the link are not up to date, some not even active any longer. – Jared Eitnier Dec 31 '15 at 3:58

I have found this http://www.gisgraphy.com/compare/ with Gisgraphy, Nominatim, Google Maps, Yahoo! Placefinder and MapQuest compare.

  • Not what I was asking for, but a GREAT tool. Thanks. – TomSchober Jun 7 '13 at 18:24

Rather late, but we at NetToolKit have invested a lot to build a geocoding comparison tool (released late 2018). The tool is primarily oriented around comparing accuracy of results (you can see how far one result is from other results by clicking on it and checking the legend), but the table below also highlights cost differences and differences in terms of service. We compare several providers, including OpenStreetMap/Nominatim, PostGIS, and the US Census geocoder. If you have any feedback, please let us know.
