摘要
Abstract
The extraction of mineralization and alteration information by remote sensing technology has obvious advantages and better effect in the northern area of Madagascar where is rich in mineral resources but sparsely inhabited,inconvenient traffic and sparsely vegetated.In this paper,the information of mafic-ultramafic rocks was extracted by principal component analysis method from band 2,4,5,6 of Landsat 8 date.Then,the quantitative inversion model of Fe concentration was established by using partial least squares regression method based on hyperspectral date measured in the laboratory.The model was used to calculate Hyperion date,and the anomalous information of Fe concentration was extracted in the study area.Finally,according to the integrated anomalous information and results of field investigation,we determine the distribution area of mafic-ultramafic rocks is the prediction areas of which the area with higher Fe concentration is the key prediction area.关键词
