Snow area detection by using AVHRR/NOAA
Comparing the AVHRR/NOAA data with snow information on the ground, a scheme for the detection of snow covered area is discussed. The studied area is the Tohoku district, northern Japan, where 169 ground truth data points are located. Firstly, an image on 15 February 1989 is analyzed in detail. A scheme of snow area detection is obtained and some mismatch points are explained. Secondly, parameter change is studied from January to April 1989. It is confirmed that a set of threshold parameters varies under the influence of the solar elevation.<>
