When you want to compare two datasets, for example if there is ongoing construction you can compare two images (ortho images) by selecting the curtain at the bottom of the screen

When pressed a white vertical line now spits the screen and you can drag this line to the left or right. To adjust what you see on the left screen adjust the time sliders (blue arrows) left part at the bottom to show the data you want on the left and do the same on the right.

<aside> 💡

Remember newest data is always shown at the top. Turn it off by not having it in between the two “blue arrows”

</aside>

The space between the blue arrows (the Movable selector) is used to filter out data by time to show. The data points show a dataset on the time axis.

This would look something like this:
