USAGE OF DIFFERENT SPECTRAL BANDS IN AGRICULTURAL ENVIRONMENTAL PROTECTION

Hyper and multispectral imaging systems widely used in agricultural and environmental protection. Remote sensing techniques are suitable for evaluating environmental protection hazards, as well as for agriculture resource exploration. In our research we compared aerial hyper and multispectral images, as well as multispectral digital camera images with the background data in the test site. Hyperspectral records were obtained by a new 79-channeled aerial /DAIS 7915/. We made additional images with a TETRACAM ADC wide band multispectral camera. We have chosen an farm as test sites, where intensive crop cultivation takes place, so soil degradation and spreading of weeds can be intensive as a result of land use and irrigation. The first objective of this study was to evaluate the applicability and usability of the multi- and hyperspectral images in large spatial resolution according to the prescription of NAKP (National Program of Agi- Environmental Protection). Multispectral analyses were complied for to evaluate the solidity of supervised classification. During the analyses of the images, the spectral characters of various vegetation types and possibilities of their classification as well as the spectral identification of the ecological buffer zones and filtering areas and their GIS interpretatio
