The following document explains the Nearmap feature called Split View or Compare two dates. This feature allows you to compare imagery for a location across two different surveys, so that you can easily see the changes over time.
In MapBrwoser, simply click the Split View button located next to the date box:
Can I view different imagery in one side, say Oblique on the left and Vertical on the right? —
Currently, it's only possible to view the same base layer type in both the left and right frames.
Can I take a snapshot or export the split view? —
Currently, you can't snapshot or export the split view. You'll need to take a screengrab using tools on your PC or device.
Can I view a different location in each side of Split View? —
No, the intention of split view is to allow you to compare the same location at different times.
