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 interpretation were investigated. INTRODUCTION For environmental state assessment and score of the areas involved in the Program, data sources with large spatial resolution are worth to apply. To distinguish the commonly Among the aims of the National Program for Agri- small fileds from the island-like vegetation spots inserted in Environmental Protection (NAKP) the principles of a the culture land the traditional methods (CORINE) are not sustainable landuse matched to the facilities of Hungary's suitable any more. Our study's aims are to evaluate the different regions are declared according to the Union's applicability and usability of the multi- and hyperspectral 2078/92 directive (Angyan et al, 1999). The farmers who images in large spatial resolution according to the have joined the above mentioned program for to gain the prescription of NAKP. During the analyses of the photos, the support cannot lead their farms without considering its spectral characters of various vegetation types and principles in connection with environmental protection and possibilities of their classification as well as the spectral nature reservation. Assignation the suitable landuse system identification of the ecological buffer zones and filtering means a serious problem, but to control whether the areas and their GIS interpretation were investigated. regulations are kept or not is much more difficult. To the right application of this supporting system the investigation of the biotical and abiotical environment surrounding the MATERIALS AND METHODS cultivated lands is needed. Environmental information can be obtained by classifying air- and spaceborn remote sensing Test region images. Knowledge of changes in land cover is becoming increasingly important from both the ecological and The investigated area is situated in the eastern part of the economical point of view (Janssen et al, 1990). Hungarian Great Plain, next to a small rural town called Hajdünánás. It has a special location being on the border of There is an increase in the use of remote sensing two geographical regions. On one hand, it is continuous with technologies. Image interpretation is faster and less expensive the area of the Hortobágy, a typical solonetz-type salt- than conducting ground survey (Floyd, 1996). Remote . affected area of the country. On the other hand, the area of sensing data have been used to detect and classify vegetation the Hajdüság loess field characterized by chernozem-type using supervised classification, cluster analysis, decision soils also reaches the region. Its climate is mainly continental, trees, neutral networks, etc. (Carpenter et al., 1999; DeFries strictly saying wet-contitnetal with 9,9"C mean temperature. & Townshend, 1994; Friedl & Brodley, 1997; Martonchik, The annual average rainfall takes 580 mm, which’s 1994; Running et al., 1995). inhomogeneous distribution often causes inauspicious conditions in agricultural point of view.
