Google Geolocation API
The code for an API call is given in scripts/connect2googlegeo.py
The Google Geolocation API allows you to use the use of a search comparable to a Google Maps search request. Google searchs for the most probable result and returns the coordinates which would usually be displayed on Google Maps. The lat and long coordinates can be extracted from the returned json file and if stored in a csv easily be loaded in an GIS. The key given here is just for testing and to get an understanding for the functionality. Please use your own key for bigger geolocalisation projects.

Note: One API is restricted to 2500 requests per day! The Tool will then stop and you can either add another key or wait till the next day and restart the Tool. Already geolocated adresses will be skipped!
