As part of ongoing commitment to provide the richest, most up-to-date, and accurate maps possible, Google began allowing users to move map markers to improve address precision, and add locations, previously in the US and Canada. Now, Google've updated the base map data in all Google Maps products and services for countries: Australia, Austria, Belgium, Denmark, Liechtenstein, Netherlands, New Zealand, Norway, South Africa and Switzerland.
"The new base maps will've features such as expanded geocoding coverage, more detailed water bodies, university campuses, zipcode and postal code coverage -- all leading to better, more accurate maps for your employees and customers.
You'll find "Report a Problem" link on the bottom right of Google Maps (you can also find it by right-clicking on the map) in these countries, enabling you to tell us about errors and changes directly for faster Maps updates. It's highly recommended that you re-geocode all of your data to take advantage of the new updated data," explains Google.
