Tree Shadows v2.1.1

TTC Solutions: Tree Shadows

About the Software

Tree Shadows predicts the position of a shadow, for any time and place. When the data is entered, the top and bottom positions of the shadow are calculated, along with shadow area and plotting coordinates. The application requires several parameters to work (see screenshots below). You first need to know the latitude and longitude of the location of the tree. The more accurate your coordinates, the more accurate the results. One-tenth degree accuracy is very good, although a difference of one or two degrees is not usually significant. Time zone is also needed.

Enter the data, and Tree Shadows will calculate and display the position of the top and bottom of the shadow, the length and width of the shadow, and the estimated area covered by the shadow.

Measurements of the tree include the height, branch spread, and the Live Crown Ratio, the percent of the canopy with live branches compared to the total height. In effect, this is the height of the lowest branches on the tree.

Tree Shadows will also determine where on a vertical wall the shadow will fall. To accomplish this, you need to know the distance from tree to wall, the direction the wall is running, and any slope of the ground between tree and wall. This can be very useful in predicting how much shade a tree offers to a nearby building.
