Atmospheric particulate blurring effects on Thematic Mapper data for areas with different particulate concentrations were studied through analysis of field edges. Edge gradient and Fourier techniques were utilized to determine the overall atmosphere-sensor system line spread function (LSF). The sampled edge data were first fitted to a theoretical curve and then processed by a lowpass filter (LPF). Two parameters of the LSF, the equivalent width and the absolute equivalent width which is defined in this paper, were calculated for several sampling regions. In most cases, the results showed that a broader width (either equivalent or absolute equivalent) corresponds to higher particulate concentration and vice versa. |
