Abstract

T[e area of total clouds cover from visible images ofMETEOSAI (7) was estimated in this research , by calculating theprobability of the ratio taken from digital image classified by thesupervised classification wh.ich is depend on maximum likelihoodclassification ,depending on the value of spatial resolution forvisible image 2.5km to each pixel element and the image size ofstudy area (1000 X 1000)pixel. lt was found that the total aroa
