利用GIS复合AVHRR数据进行积雪信息提取方法的研究

A Preliminary Study on Snow Mapping Using AVHRR Data and GIS Techniques

自从遥感技术出现以后,积雪遥感制图逐步发展起来,其方法也多种多样。近年来,利用多波段遥感数据进行积雪制图的方法被采用得越来越多,并且显示出很大的优越性。利用当地气象卫星地面站接收的AVHRR数据资料,探讨在微机环境下进行积雪遥感信息提取的方法。并利用GIS技术实现遥感信息和地理信息的复合,获取更加丰富的雪盖信息。

Digital snow mapping using satellite data has been developed since the advent of remote sensing, and a wide variety of methods have been proposed. In resent years, the method of multispectral classification has been developed and shows more advantages in snow mapping application. In this paper, the snow mapping method using AVHRR data is discussed, and the basin-wide and zonal snow mapping with the aid of GIS is also investigated.
