The methodology and results of the digital analysis of multispectral space imagery LANDSAT 7 ETM+ are considered, namely the calculation of NDVI index and isolation of principal components. The meaning of the latter has been analyzed by the calculation of their correlations with spectral channels and relations to the main vegetation types. Key words: multispectral geoimagery, vegetation index, principal component analysis, geoinformation analysis.
