The investigation of vegetation growth vigour on south ion RE minerals areas is carried out by using high resolution Quickbird data of remote sensing,the methods of density slice based on normalized difference vegetation index and vegetation greenness of rotating planar scanner plots are applied,the two methods are compared and analysed.

In a research on "new technique applications of groundwater exploration in water deficient regions at the western of Liaoning province", Landsat7 ETM image was used as data source of drought period in this paper,multi-band data were used by analysis functional module in image processing software, for Principal component analysis, Stretch data, Enhancements, Density slice,etc.
