Feasibility of using multi-channel methods has been grounded; the results of three channel method have been analyzed on the basis of measurements data of B1, B2, B3 channels of SPOT XS and X1hardware. A certain three-channel criterion for detecting coastal line is transformed into an index-channel type criterion. It has been shown analytically that the considered criterion possesses more sensitivity in regard of variations of B1/RED than of variations of NDVI. It has been graphically presented that sensitivity of used criterion in regard of S1/RED is at least two times more than in regard of NDVI. This fact testifies non-correctness of NDVI utilization for determination of coastal lines.
