Urban Sensing by Hyperspectral Data
نویسندگان
چکیده
The airborne hyperspectral imaging data has operationally been used in environment, geology, agriculture and other fields. In this paper, airborne hyperspectral data in visible, SWIR, MIR and TIR spectral region acquired by the 128 band Operational Modular Imaging Spectrometer (OMIS) was attempt in urban object identification. Natural grassland/artificial grasslands, and different types of metal slabs in construction roof have been successfully differentiated, respectively. Combined with Geographic Information System(GIS) technology, a large scale urban mapping by using airborne hyperspectral data was also discussed in this paper. The results suggest that hyperspectral imaging data, especially combined with short wave infrared and thermal infrared, has broad application perspectives in artificial object identification and urban investigation.
