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 the New MapBrowser, simply click the Split View button located next to the date box:
If you are a US customer, please refer to the last section on this page.
A convenient way to compare changes between two dates is to use the Time Compare tool found in the upper right of the MapBrowser. This works in either Vertical or Terrain mode.
Just click the clock icon and you'll see a slider appear on the map, as above. If you click and drag the blue double-arrow marker on the slider, you can slide the view back and forth between the two dates selected.
To choose the dates to compare, just click one of the two dates shown and a list of the other options will appear for you to choose from.
If you double-click the blue double-arrow marker in the center of the slider, it will switch orientation so that the map is split horizontally instead of vertically.
To deactivate the tool, just click the clock button again.
An example of Time Compare in use:
You can compare imagery of the same location from two different dates using SplitView.
To view imagery from different dates side-by-side with SplitView:
- From the Toolbar, select View.
- Select SplitView. The Split view control panel appears.
- In the Split view control panel, ensure that Enable is checked.
- At the Date comparison dropdown on the left, select an imagery date to display.
- At the Date comparison dropdown on the right, select another imagery date to display.
- At Mode, select Vertical if you want to split the screen vertically between your chosen imagery dates (one date on the left, and one on the right). Select Horizontal if you want to split the screen horizontally (one imagery date on top of the other).
- Hover your mouse over the slider control and drag it either way to reveal the imagery you want to see.
