Comparison of internal area relative reflectance and 6SV reflectance calibration for impervious surface detection

Objective of this research is to compare performance of the Internal Areal Relative Reflectance (IAR), and Second Simulation of a Satellite Signal in the Solar Spectrum (6SV) surface calibration methods for discriminating impervious surfaces in urban settings. We used EO1-Hyperion image of Pune city recorded on April 2013. We converted the radiance values to reflectance using IAR and 6SV and then classified image in to Vegetation, Impervious surface, and Soil (VIS) classes. Preliminary results indicated that 6SV does not provide any advantages over IAR. Average overall accuracy of classification over 8 different experiments was increased by ∼1% for IAR.
