A snow survey in north-west China has been carried out using meteorological satellite NOAA-9 imagery. A two-step geometric correction method is presented. The first step involves a large-scale geometric correction, and the second step concentrates on a small area of interest, using the control-point correction method. A high precision of geometric correction can beachieved by using this method. The snow-covered area of the Qilian Mountains basin is calculated.
