| Alteration Remote Sensing Anomaly ExtractionBased on Aster Remote Sensing Data |
| Mineralization alteration remote sensing anomaly has been perfected based on ETM+/TM data, but al-teration remote sensing anomaly extraction achievement is very poor based on ASTER(Advanced Spaceborne Thermal Emission and Reflection Radiometer) remote sensing data. In the study, we have rebulit alteration miner-alization spectral curves on ASTER remote sensing data based on representative alteration minerals reflectivity data in USGS standard spectral database. We think that four types ions information which are Mg-OH, Al-OH, CO32? and Fe3+ can be extracted. In the paper, a practical application example for Chengde area and Taihang-shang area in Hebei province as example, we have used modifying “de-interfered anomalous principal component thresholding technique flow” to extract the four types of ions information. The results of four types of ions infor-mation be extracted are same to the investigation in the field, which shows extracting the four types of ions infor-mation based on the ASTER remote sensing can be accepted. |
