Using Map tools in the Widget, you can view parcel imagery in different ways, on different survey dates and also view a parcel on two different dates.
Viewing different content types
Use the Base Layer picker to choose the imagery, also referred to as content type, you want to view. Each of these content types is explained in more detail in Widget Content Types.
|
| Base Layer | Description |
|---|
| Vertical | This is the standard, fully orthorectified overhead aerial map. |
| Panorama | Offers a 45-degree angle view of a location, when available. Y ou can view Panorama imagery for each cardinal direction of the location using the compass tool. |
| Terrain | View the terrain of the location. It can be very helpful to switch Street Maps or Properties on while viewing the terrain map to make navigating the map easier. |
| Oblique | Provides a 45 degree angle view of a location. Oblique imagery differs from Panorama in that you view individual photos of an area, rather than a continuous, blended vertical imagery. |
| Roads | Shows a view of the street maps only, with no aerial imagery visible. |
| TrueOrtho | Shows continuous ortho mosaic implementation of the True Ortho option provided through 3D Export. |
| 3D | Displays the imagery in Cesium format. |
As a default, any area of interest is displayed from the latest available capture. However, you can view historical captures with the Date Selection tool. To do this
- Zoom to your area of interest.
- Click the Date dropdown list.
- Select a date to display.
The capture from the date you selected is displayed. Nearmap imagery is high-resolution, and may take a few seconds to load.
Comparing surveys
The Widget allows you to compare imagery for a location across two different surveys, so that you can easily see the changes over time. It is only possible to view the same base layer type in both the left and right frames.
To compare surveys, click the Split View button located next to the survey date. Select the required survey dates in both frames.
Currently, you can't snapshot the split view. You'll need to take a screenshot using tools on your computer or device.
Comparing AI attributes
Take advantage of split screen when viewing an AI layer where there is more than one capture date. You will be able to bring captures from two generations into view on either side of the split screen. It can be a handy way to perform visual change detection. By swiping the slide back and forth with the background darkened, you see the coloured blobs appear and disappear where change has occurred.
Note that you will need to purchase AI packs to be able to do this.
