What do you think of the previous satellite sites?

The method is as follows:

1, open Google Earth, first find the place you are looking for, and select the timestamp.

2. After the time mark is selected, the time selection slider will pop up. The left and right sides of the time stamp represent the age area of the pictures that can be seen, and the satellite images of 1930 to 20 16 can be seen. The date above represents the date currently displayed in the map. Slide the slider to select different times and view satellite maps at different times.
