Anyone would agree that Google Earth is very helpful, particularly in providing directions. What you see on a street view may not be in real time, but it is current enough. In the event that you are looking for a particular establishment, or finding your way back where you came from, Google Earth can lead you to the right direction.
It is even more helpful in showing the full extent of the recent Louisiana flooding. What programmers had to do was find the most recent Sentinel image captured, which was taken on August 14, 2016. The picture offered an insight as to the extent of the flood, with some areas taking most of the water. Just looking at the images will show you how far the damage has reached.
But Google Earth has one major flaw; its elevation data, particularly in mountainous areas, is inaccurate.
In a post on Google Earth Blog, avid Google Earth user Timothy Whitehead, checked the validity of the claim by comparing an image of the Sugarloaf Mountain in Rio de Janeiro with the 3D turned on and off.
When 3D is turned off the peak of Sugarloaf Mountain is at sea level with a 0 m elevation, but when it’s turned on, it actually shows an elevation of 460 m.
The peak of Christ the Redeemer, on the other hand, showed and elevation of 500 m with 3D turned off, and about 700 m when it’s turned on. So there’s a difference of 200 m. But when an elevation profile is done based on the route to the summit at the statue, it showed a dip in elevation of 100 m, when it should have been 700 m.
Despite these inaccuracies in elevation data, Google Earth is mostly accurate. This is why you should get the best of it wherever you want it.
