摘要:
A snow survey in northwest China has been carried out using meteorological satellite NOAA-7 images. A two-step geometric rectification method is presented. The first step involves a large-scale geometric rectification and the second step concentrates on a small area of interest by using the control point rectification method. A high precision of geometric rectification can be achieved using this approach. The snow covered area in the Qilian Mountain Basin is calculated.
