Summary: The article discusses advantages and disadvantages of ultrasonic hypsometers compared to the hypsometers used so far. Due to minimal divergence (78 % divergence of ± 5 cm) in measuring horizontal distances in relation to the measured real distance, the Vertex hypsometer can be used as a distance measurer in forestry operations. The heights of some trees differed considerably when measured with different instruments. Differences in height were predominantly the result of differences in determining horizontal distances with a given instrument. The largest differences or total errors (SEr) in height measurements in relation to the Vertex, which was used as a control instrument due to its accuracy in determining horizontal distances and heights, were found in Blume-Leiss - 0.012 m, Bitterlich’s spiegel relascope with standard scale - 0.161, Bitterlich’s spiegel relascope with CP scale – horizontal scale - 0.271 and Bitterlich’s spiegel relascope with CP scale – vertical scale - 0.301 m.
Key words: accuracy; determining horizontal distances; determining tree height; ultrasonic hypsometer |
