Conteúdo: | Quality land cover data for large areas are important to many decision making processes concerning the environment and natural resources. Integration of remotely sensed data is often the best way to obtain such information. Airbone Visible-Infrared Imaging Spectrometer (AVIRIS) data were collected during early September, 1991 for the Indian Pine Natural Resources Field Station located just west of West Lafayete, Indiana, U.S.A. AVIRIS is the next generation of remote sensing instruments and is proposed to be placed on the space station. The spatial resolution of the AVIRIS data is 20 meters, which is higher than the spatial resolution of LANDSAT Thematic Mapper (TM) data; the spectral resolution is 10 bits, which is higher than the spectral resolutions of LANDSAT TM and SPOT. The AVIRIS data had 224 spectral wavelengths, each with 10 nm band widths in the electromagnetic region of 0.4 to 2.45 um. The data were analyzed for study of land cover for the Indian Pine area. By classifying AVIRIS data, we can obtain more accurate and detailed information than previously possible for land cover and high quality timely information for use in geographical information systems.
