Ky. Kondratev et Pp. Fedchenko, PROPERTIES OF A METHOD FOR SPECTROPHOTOMETRIC MEASUREMENT OF NATURAL OBJECTS, Soviet journal of remote sensing, 11(1), 1993, pp. 20-36
A method for ground measurement of the spectral brightness coefficient
s of natural formations is described, Results obtained using this meth
od are used to calibrate aerospace remote sensing data. Various aspect
s of the method are discussed (choice of a standard reference, viewing
angles and the height of the Sun, sizes of test areas, wavelengths, s
pectral resolution, etc.) and a number of practical recommendations ar
e given.
