KNOWN SPECTRAL SIGNATURE OF LITHOGRAPHIC LIMESTONE

                

Based on the chemical composition of slag, lithographic limestone exhibits the most similar published spectra (ASTER website). Upon resolving the conflict with the IDRISI software, this page will be update to show the actual reflectance for the slag test site.  

The following table shows the spatial and spectral resolution for the ASTER satellite.
