Abstract

An evaluation of a hand-held electronic laser-based surveying instrument was carried out for stem mapping of trees in forest plantations. Results obtained from field tests of the hand-held device and a standard surveyor's total station are compared. Theoretical and practical working distances for a specified accuracy level are presented and discussed. The maximum theoretical working distance to maintain an accuracy of 25 cm at the 99% confidence level is 47.7 m, and the practical working distance on a plot with a tree spacing of 2.4 m and with a slope of 25° is approximately 20 m.
