Google continues to push out new 3D imagery on a regular basis. However, an increasingly large proportion of it is updates to areas that already had 3D imagery. The updated areas are generally better quality and certainly welcome, but it does mean there is a noticeable decline in the amount of new area covered each month.
New area in square kilometres of 3D imagery covered by month. Note that we have not yet included all of the January and February, 2016 areas.
To see the area covered by 3D in Google Earth download our KML map.
We used to use the helpful online tool at Zonum Solutions to calculate the areas. However, it has a file size limit that our KML file has exceeded and a few other issues which make using it for our particular requirement quite tedious. So this time we used the area functions found in GeographicLib to do the calculations.
The US has almost double the area of 3D imagery of the rest of the world put together.
Note that some 3D areas overlap borders and the areas are recorded in the country/state where the bulk of the 3D lies. So Rhode Island State, for example, does have 3D imagery but it is part of a large area mostly in Massachusetts.
Thank you to all the GEB readers that find new areas and a special thanks to the GEB readers who draw new areas for inclusion in our map. New areas are noted in the comments of this post. If you wish to submit outlines please first read through the instructions found here.
