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.

    Looks like I need to add that. Give me a little time.

    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.

    @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.

    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

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 Dec 31, 2015 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. Dec 31, 2015 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.

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.

My company https://bettermile.com/ does benchmark multiple geocoders on a consistent basis with millions of addresses we receive from parcel delivery companies in Europe, mostly Germany, Italy, Spain, Austria, the Netherlands and more recently Canada.

Here’s a sneak peek of what we have seen so far with Google, Here and Mapbox. I also included our product because why not :), but the results look like this.

Accuracy Level BetterPlaces Google Here Mapbox
HIGH 97.90% 97.65% 96.89% 69.30%
MEDIUM 1.02% 1.37% 1.96% 27.97%
LOW 0.34% 0.98% 1.10% 2.73%

The accuracy levels mean:

HIGH: The result is accurate to the house number, the building (rooftop coordinates) or to a Point of Interest level.

MEDIUM: Accurate to the closest street or in front of the building

LOW: City, town or locality

There are a few of things to mention:

  • These are averages of all the multiple benchmarks we have done in the last 6 months or so, all of them with millions of addresses, and all of them across different area types (urban and rural)
  • We apply normalization to the addresses before sending to the different geocoders, which means that a lot of corrections have been made and hence the quality of the result and the success rate is significantly higher.
  • Without normalization you can discount at least 5%-8% from Google, Here and Mapbox. BetterPlaces always applies Normalization.
  • Some geocoders are stronger in rural areas, namely Here have really good data there, however Google offers a higher amount of successful geocoding results.

I've noticed a lot of these comparisons don't include Geocode.Farm. Just wanted to mention it's free for 100/day and paid monthly plans for over that starting at 10€ even.

https://geocode.farm

It is a really simple to use API and I'm not sure why nobody is including it in their comparison tools. Would be nice to see a comparison.
