Single Tree Shadow Area Analysis

As part of the ArborShadow Accuracy Tests.
 
For this test I first created 11 tree shadows using different canopy dimensions projected for random times of the day. The values produced by ArborShadow were compared to those produced by AutoCAD.

The difference between each value was then calculated as a percentage of the AutoCAD value and plotted (see below).

The difference for each sample is tiny (less than quarter of 1 percent).
