Abstract :
Paper describes a methodology to process, analyse and compare hyperspectral remote sensing data for mapping vulnerability in urban areas. Spaceborne and airborne imaging spectrometers are used to develop this model. A high precision spectral library of pure materials over an urban scene in Sydney was created by using a spectroradiometer. Hyperspectral images were corrected for radiometric and atmospheric disturbances and calibrated before classification by a supervised method. Results include the creation of a detailed high precision spectral library of urban surface materials. Other results include an integrated model which was developed by combining with other GIS data for providing decision support systems.
