摘要
为了提高卫星云图在天气预报中应用的及时有效性,经常需要尽快显示实时接收的卫星数据云图。各省气象台中规模利用站接收的FY2C卫星云图的实时数据,格式为gpf,需要先进行通道分离后才能显示图像,本文主要介绍各种投影类型的gpf数据经通道分离后,对其单通道云图进行小波分析,以便简单直观地分析云图的特征、提高云图的传输效率。
Real- time Data image of FY2C Satellite is displayed as soon as possibe, in order to improve the efficiency of wether forcast in time, the form of real - time data form FY2C Satellite above Qinghai area is gpf, which must split the channel for display image,the paper mostly introduces the channel split to every projection type of gpf data, then introduces wavelet analysis on the images of single channel for analysis feature of image,easily and directly,on the other wise, improve the transmission efficiency of image.
