Web.Google.Geocoding

This package has no connection with Google Inc. or its affiliates.

The Google Geocoding API provides a direct way to access geocoding and reverse geocoding services via an HTTP request. This library provides bindings in Haskell to that API.

NB: The use of the Google Geocoding API services is subject to the Google Maps Platform Terms of Service, which terms restrict the use of content. End Users’ use of Google Maps is subject to the then-current Google Maps/Google Earth Additional Terms of Service at https://maps.google.com/help/terms_maps.html and Google Privacy Policy at https://www.google.com/policies/privacy/.

The code below is an example console application to test privately the use of the library with the Google Geocoding API.
