Topology in a fruit plantation

Localization of fruit trees, topology of their branch structures and spatial structure of their canopies arecrucial in the planning of site-specific agro-ecological and production technology projects in an orchard.Instruments and technologies currently used in precision agriculture and horticulture provide opportunities forobtaining information about the characteristics of fruit trees given above. The study area was an intensive appleorchard on the Study and Regional Research Farm of the University of Debrecen, near Pallag. Examinations werecarried out with two active remote sensors. Spectral properties of the investigated trees' canopies were sampledusing a GreenSeeker 505 Hand Held? Optical Sensor Unit, and the collected spectral dataset was supplementedwith the results gained by a Leica ScanStation C10 3D laser scanner. Based on the spectral characteristics of the vegetation, the created vegetation index map indicated differences in the vigor between the trees. While the highresolution scanning made possible to detect the positions of the fruits on the trees as well as their locations andvolumes. The integration of the two special data collection systems provides new opportunities in the developmentof a precision plant production syste
