Use Of Hyperspectral Data for Environmental Monitoring
New generations of satellites and entry of the private sector into space research and to remote sensing data market brought along re-interest in remote sensing. The resolution of contemporary satellites competes with photogrammetry in many respects and development of technologies combining active and passive detectors and also new processing technology can be expected. Hyperspectral scanning is one of the new lines in remote sensing, it generally consist in reflectivity measurement in tens or hundreds of spectrum bands and in the comparison of the course of reflectivity with reference standards. This way provides significantly better classification of objects of the land surface and their state. In addition to several aerial scanners, there is only one civil hyperspectral satellite carrier – satellite Hyperion. Similar to hyperpectral scanning is only the Terra satellite (Aster sensor), which can be used especially for geological purposes. In frame of the project of Czech Ministry of Environment we study the possibilities of utilization of these data in Czech Republic. The project is aimed at processing and completion of a unique satellite data set acquired by Hyperion and Terra satellites over the central, northern and western parts of the Czech Republic. These areas are heavy damaged by brown coal output in open casts, in last years by flooding and a long time by chemical industry. The project represents an analysis of new possibilities of contact less documentation and survey of ecologically sensible sites. The paper will refer about first outputs from Geomatica 10 and ENVI software’s.
