Rephotography

Rephotography is when you take a photograph of a place or thing that was once photographed before. So, for example, if someone took a photograph of a park five years ago, you could take a new photograph of the same park five years later and compare the two photos side by side. You can see what has changed in the park between those two times. Rephotography is used to show changes in the environment over time.
