摘要
In vegetation covered seriously field, based on synthetic spectral information model, the study on hyperspectral remote sensing information extraction for alteration mineral has been carried on. Taking Dayingzi field, Chengde City, Hebei Province as an example, based on the spectral curve difference between alteration minerals and background objects, the alteration mineral distributing information of chlorite, clinochlore, calcite and dolomite has been extracted based on Hyperion data in the field of vegetation covered more than 70 percent. The extracted alteration mineral distribution information is the same as the geology and mineral resources data conformed in the filed. At last, combined with the remote sensing geology interpretation result and relative geology information, with the combination distribution characteristics of the alteration mineral, the further favorable exploration area was delineated.
