ABSTRACT - Few studies have beem carried out to understand the spectral response of agricultural areas in the microwave region, particularly for sugarcane.This study aimed at investigating the magnitude of influence of planting row direction in the L-band ALOS PALSAR imagery (A ~ 23 cm). First of all, sugarcane plots in the study area were grouped according to their cutting stage and varieties. Then, they were classified as parallel or perpendicular to the range of the satellite. This was done using contour lines identified in high-resolution images of the study area. The digital values of the amplitude images, along the crop cycle, were transformed into backscattering coefficients (o0) and the images were georeferrenced using control points obtained from Landsat geocover image. The results showed an average variation of dB over sugarcane plantation rows varying from parallel to perpendicular to the range direction. Therefore, an effective image processing technique needs to be developed to correct row direction effects in PALSAR images in order to obtain improved maps of sugarcane plantation areas and biomass. |
