Measure tree crowns, overlaps, exclusions, and canopy compliance. Built for planners, estimators, and site teams. See totals instantly, then export tables, charts, and summaries.
Use this sample to understand how grouped trees, overlap, and target coverage interact in a construction planning workflow.

Keep all dimensions in the same unit system. Area outputs will follow the square of that unit.
Tree canopy coverage is the share of a site shaded by tree crowns when viewed from above. It helps planners estimate landscape performance, environmental value, and whether a development meets municipal or project canopy targets.
Excluded area removes zones that should not be counted in the compliance denominator. Typical examples include restricted utility corridors, preserved structures, or other spaces your project standards tell you to exclude.
Use a circle when the crown spread is fairly uniform in every direction. Use an ellipse when the canopy is longer in one direction, such as along a street edge or near building setbacks.
Condition factor adjusts the canopy area for tree health, pruning, damage, or incomplete crown form. A strong specimen may justify a higher factor, while stressed or heavily pruned trees usually need a lower one.
Growth factor lets you model future canopy scenarios, not just current crowns. This is useful when construction documents, landscape schedules, or local rules consider expected maturity instead of present-day spread.
Overlap reduction subtracts duplicated crown coverage where adjacent tree canopies intersect. Without it, grouped plantings can overstate actual site coverage. Use a realistic percentage based on spacing, species form, and design intent.
No. All site dimensions and canopy diameters should use the same base unit in one run. Mixing units creates distorted areas and inaccurate percentages because area scales by the square of each unit.
Review the reported shortfall, then test added trees, larger future crown assumptions, or lower overlap. The calculator also estimates how many average trees may be needed to close the remaining canopy gap.
