Abstract. We developed a setup for fully automated, high-frequency in situ monitoring system of the stable water isotope deuterium and 18O soil tree xylem. The was tested 12 weeks within an isotopic labeling experiment during large artificial sprinkling including three mature European beech (Fagus sylvatica) trees. Our allowed one measurement every 12–20 min, enabling us to obtain about seven m...

An essential function of the multimedia DBMS is to present objects of the query result according to their temporal-spatialrelations. These relations can be specified within the database schema on the class level and used for each object presentation. In case of partial extraction, however, the retrieved objects may not belong to an existing class, but belong to a newly created class which does ...

This study explores the feasibility of applying single-scan airborne, static terrestrial and mobile laser scanning for improving the accuracy of tree height growth measurement. Specifically, compared to the traditional works on forest growth inventory with airborne laser scanning, two issues are regarded: "Can the new technique characterize the height growth for each individual tree?" and "Can ...
