I've been experimenting with the new Google Reverse Geocoding which allows you to get the location name and country and stuff from a latitude/longitude coordinate.
I wrote down a list of about 15 lat/long points and the result I expect from them (taken from an existing app I'm contemplating switching to Google Reverse Geocoding for) and ran a batch of timed tests on. These results might satisfy the impatient:
FAILURES: geonames_json 0 google 0 geonames 12 TOTAL TIMES: geonames_json 2.43582677841 0.143283928142 seconds/request google 2.24999976158 0.132352927152 seconds/request geonames 1.78063511848 0.104743242264 seconds/request
First of all, a "failure" is when the place name simply can't be looked up. You could consider certain results a failure but it depends on what you intend to do with results. For example, GeoNames returned
Glen Mills, United States whereas Google returned
38 Hitchcock Ln, Glen Mills, PA 19342, USA. With the Google results it's not always obvious that the "place name" (alternatively the town) is the second to last bit split by commas.
Using geopy to connect to GeoNames is clearly a bad idea. It's much better to just connect directly to the JSON REST URL.
In conclusion, I'm not going to change from using the GeoNames JSON API to Google Reverse Geocoding in my app.
