| Abstract: | ASTER Remote sensing data have a good prospect in the abnormal alteration mineral extraction and exploration as a result of wide-band range and multi-band.According to the metallic mineral deposits commonly altered spectral characteristics and the characteristics of the band of ASTER,the Ferrous silicates,Ferrous iron Fe~(2+),dolomire,and other mineral extraction of the spectrum index were made.On this basis,the Atmospheric correction and removing interference were studied.The unusual extraction technology processes and procedures were built.Tianhu Iron Ore in Xinjiang Tianshan Mountain were study,the results showed that extract and process data-processing techniques are more reliable. |
| Keywords: | ASTER Radiometric calibration Atmospheric correction Anomaly Extraction |
