Google photos is an online photo album service I have been using. Apart from unlimited space, the biggest surprise is that the system automatically creates content. After the recent revision of Google photos, in addition to changing the logo, it has also added the thermal map function, which makes the display of photos on the map, a function that everyone has, become different.
 

It's very common to display photos on the map. A classic way to display photos is to mark small photos on the map directly. The number of photos is shown in the upper right corner of the map. In fact, it looks a little stiff now. The other is not to display the map, but to categorize the photos directly by text.
 

The photo thermal map of Google photos is to display photos on the map in the form of points. The bigger the point is, the bigger the photo is. Finally, a thermal map is formed.
