Abstract: Highlights•The DS and KS algorithm were employed to calibrate GF-5 imagery.•The constructed 2D-SSI performed well in highlighting characteristic bands.•CARS algorithm coupled with significant correlation method can retrieves features.•Distributions of Pb, Cu, Cd, and Hg were mapped with the corrected GF-5 imagery.
