Crown Profiler

Generating shade profiles for every tree can be done with ease. The alternative shade profiles can be generated as location, crown size, form and density are varied.

Crown Profiler provides:

• Shade profile of any inventoried tree location
• Single or multiple tree shade profiles with the "click of a mouse"
• Time/year/month specific shade profiles
• Managers with real situations and facts that effect turf health and conditions

The tree Crown Profiler application calculates shade profiles produced at ground level. For a given latitude, longitude, date, time, tree shape, and size, a shadow polygon is created representing the shaded area. Shade pattern calculations have be integrated into Point DataMap to provide a state of the art GIS (Geographic Information Systems) application.

Standard formulas are used to determine the position of the sun (altitude and azimuth) and the resulting shadows for given tree shapes.
Single Tree Profile or Multiple Trees

Using the singletree profiler tool, the user selects a tree on the living map to perform detailed shade profiling. The dialogue system solicits adjustments for the:

• Date, time, canopy spread, top canopy height, bottom canopy height, canopy density, and tree shape.
• The shade profiles are calculated on the fly as the settings are adjusted.
• A library of tree canopy shapes is provided. To improve accuracy, the tree shape can be adjusted in the tree design dialog. This dialog allows the user to click and drag the edges of the canopy to produce the desired shape.
• User can save the results as a video file for future use.

This tool requires the following attributes in the tree shapefile. All of data are collected in StrataPoint's Tree Inventory.

• Tree shape - if not provided, the default is spherical.
• Canopy width - this is taken at the bottom for pyramidal shaped trees.
• Canopy height - collected during tree inventory.
• Height at bottom of canopy - can be changed at any time to specified requirements.
