1. What is the Tree Height Calculation?

The tree height calculation uses trigonometry to estimate the height of trees in the UK. It's based on the angle measured to the top of the tree from a known distance, combined with the observer's eye height.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

Where:

• \( \text{angle} \) — Angle to top of tree in degrees
• \( \text{Distance} \) — Horizontal distance to tree in meters
• \( \text{Eye height} \) — Observer's eye height in meters

Explanation: The tangent of the angle gives the ratio of height to distance, which is then adjusted by adding the observer's eye height.

3. Importance of Tree Height Measurement

Details: Accurate tree height measurement is important for forestry management, ecological studies, and urban planning in the UK.

4. Using the Calculator

Tips: Measure angle in degrees (0-90), distance in meters, and your eye height in meters. For best results, measure on level ground and aim for the very top of the tree.

5. Frequently Asked Questions (FAQ)

Q1: What's the best tool to measure the angle?
A: A clinometer is ideal, but smartphone apps with inclinometers can also work.

Q2: How accurate is this method?
A: Accuracy depends on precise angle and distance measurements. Typically within 5-10% of actual height.

Q3: Does slope affect the measurement?
A: Yes, this calculation assumes level ground. For slopes, more complex trigonometry is needed.

Q4: What's the average eye height for adults?
A: Approximately 1.6m for women and 1.75m for men, but measure your own for best accuracy.

Q5: Can I use this for very tall trees?
A: Yes, but ensure you're far enough back to get a good angle measurement (ideally 30-45°).
