ABSTRACT:
A method of processing spectral data for the earth's surface is provided which effectively identifies areas having a high probability of containing hydrocarbons. The method involves processing of intensity values for various wavebands of radiation reflected from areas of the earth's surface which correspond to image elements called pixels. The intensity values are employed in conjunction with predetermined hydrocarbon productivity data (i.e. drilled productive, dry holes) to derive discriminant probability functions whose values for various pixels are indicative of the presence of hydrocarbons in those pixels.
