卫星云图已广泛使用多年,特别是高分辨的HRPT图片的使用,又为我们提供了更细致的信息.但工作中又可能会有新的要求.比如:一张图片上有块较强的中小尺度云团,准确的经纬度是多少?一条锋面云带,长宽有多少公里?冬、春季地面积雪能否从云图图片上估算出一个大概数值?或者,要为某个无资料的地面点提供气象服务,这个点在云图上的准确
Satellite imagery has been widely used for many years, especially the use of high-resolution HRPT images, but also provides us with more detailed information, but may also have new requirements in the work. For example: a picture of a strong block Scale cloud, what is the exact latitude and longitude? A frontal cloud band, how many kilometers in length and width? Can winter and spring snow cover estimate an approximate value from a cloud picture? Or, for a given ground point Provide meteorological services, this point on the cloud accurate
