Precision of three tree height measuring devices in forest conditions
Summary:
This study was set up to compare trees heights measured with an ultrasound device
manufactured by the Swedish company Haglöf called the Vertex III with T3 transponder. This
device is specifically made for the forestry market. The study compares a Vertex III to a
Suunto PM-5/360 and a Blume- leiss to measure total tree height. The study took place under
