Usage of Different Spectral Bands in Agricultural Environmental Protection
نویسنده
چکیده
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 multiand hyperspectral images in large spatial resolution according to the prescription of NAKP (National Program of AgiEnvironmental 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.

متن کاملEnabling Sensing-based Opportunistic Spectrum Re-usage with Secondary QoS Support
Within the last years a discrepancy between the spectrum licenses and the actual usage of spectrum has been observed. While the vast majority of frequency bands attractive for wireless communication are licensed, measurement campaigns have shown that large portions of the spectrum are temporarily unused in many locations. Sensing-based opportunistic spectrum re-usage has been identified as an a...
متن کاملTarget Detection Improvements in Hyperspectral Images by Adjusting Band Weights and Identifying end-members in Feature Space Clusters
Spectral target detection could be regarded as one of the strategic applications of hyperspectral data analysis. The presence of targets in an area smaller than a pixel’s ground coverage has led to the development of spectral un-mixing methods to detect these types of targets. Usually, in the spectral un-mixing algorithms, the similar weights have been assumed for spectral bands. Howe...
