Here's how to compare two orthophotos:
Activate the Compare Orthophotos tool.
In the scene, a dividing line is created that shows the two most recent orthophotos from the timeline. By holding down the right mouse button in the scene and dragging sideways, you can decide how much of each orthophoto you want to see.
To zoom in or out on the orthophoto, use the scroll wheel on your mouse.
To pan across the orthophoto, hold down the left mouse button and move the mouse in the direction you want to go.
If you want to change the orthophotos displayed on each side, you can do so in the right panel.
Please note that only orthophotos processed through Cloud Processing can be used in the Compare Orthophotos function.
