The first element represents a minimum value and the second element represents a maximum value. The units are the same as those of the image. The values may exceed the values in the image up to a fairly extreme limit. If, for example, PIXRANGE(2) > 100 * map max, however, the map max is used as PIXRANGE(2). Null Value: (0,0) Null value assignment usually map min to map max. PIXRANGE(2) <= PIXRANGE(1) taken as "null value". ----------------------------------------------------------------
