| Zusammenfassung |
| We present an empirical application of multispectral laser scanning for
monitoring the seasonal and spatial changes in pine chlorophyll (a + b)
content and upscaling the accurate leaf-level chlorophyll measurements into
branch and tree level. The results show the capability of the new instrument
for monitoring the changes in the shape and physiology of tree canopy: the
spectral indices retrieved from the multispectral point cloud agree with
laboratory measurements of the chlorophyll a and b content. The approach
opens new prospects for replacing destructive and labour-intensive manual
sampling with remote observations of tree physiology. |
