Over the course of 2016, Google Earth received about 90,000 square kilometres of new 3D imagery (about the area of Portugal). This represents a significant slowdown in new area covered:
New area of 3D imagery by year in square kilometres.
New area of 3D imagery by month in square kilometres.
However, a lot of previously existing areas received updates, either with freshly captured imagery or reprocessed imagery, but such updates are impossible to track in terms of area.
Three new countries received imagery this year, Tunisia, Malaysia, and most recently Slovenia.
As always, a big thank you to all the GEB readers who contribute to our KML map of 3D areas by alerting us to new areas and/or drawing outlines. If you submit outlines please be sure to follow the guidelines.
