The Nearmap Shadowing tool estimates where shadows will fall, based on the surface model calculated from our imagery. This tool is found in the Layers panel for Nearmap subscriptions that include it.
Accessing the Shadowing Tool
To access the Shadowing tool from MapBrowser:
Select the Layers tool from the toolbar, and select the Shadowing tab:
Open the Tools menu, select Assess, then click Shadowing:
For example, search for the Washington Monument, change the date to Sat Oct 25 2014, and then click the location icon to see the photo time:
Our Location tool showed that the below image of it was taken at 11:09am on the 25th of October, 2014.
Enter these numbers into the Date (DD/MM/YYYY) and Time (24-hour) fields of the shadowing tool. We opted to have the calculated shadow displayed in green for clarity, and clicked the Set button. Both the real shadow underneath and our calculated shadow are visible. You can toggle calculated shadow visibility using the Show Shadowing checkbox.
In order to determine where the shadow will fall an hour later, just change the Time field accordingly:
A key practical application of this tool is to determine where shadows will fall on a house at different times of the day or year.
The Shadowing tool uses terrain data that models the topmost surface, so it factors in trees, buildings, etc. Because it is captured simultaneously with the imagery, it keeps up to date with changing structures, even ones in the midst of construction. Shadowing is only usable on captures taken since roughly mid-2014.
