Prove di integrazione di indici di vegetazione telerilevati nei sistemi informativi per il monitoraggio della nutrizione azotata

[Autom. eng. transl.] The work examines some integration procedures in the territorial databases of information derived from multi-spectral optical remote sensing, a technology suitable for costs per unit of area and effectiveness, for spatial-based monitoring, with high temporal repetitiveness, of the nitrogen nutrition status of the agricultural crops. To this end, in a Lombard area of around 600 km2, selected on the basis of vulnerability to nitrate leaching, homogeneous parcels cultivated with maize in 2007 were identified using object-oriented analysis techniques based on multi-spectral images of a SPOT HRG acquisition of 8 July 2007 and from the SIARL 2007 agroforestry use charter. Later in the sample area vegetation index maps were produced related to the nitrogen nutrition status of the crops starting from the same SPOT HRG acquisition. A first statistic of the collected data is presented.
