Tree height

This tool aims to help you measure the heights of trees by measuring one distance and two angles.

You should start at the base of the tree and walk 10 metres away then turn around to look back at the tree. We will use your device's camera and device orientation to help you line things up (if you are on iOS 12.1+ you may need to change your Safari settings to make this work).
