Abstract :
A project was designed to evaluate the applicability of RADARSAT-1 multitemporal and multiangle data for the discrimination and mapping of tropical landuse/landcover. Five fine beam mode images were acquired over the summer of 2001 for F1, F4, and F5 angles. Principal Component and texture analysis were applied to backscatter images. The results indicate that the texture (mean vector) images spanning the growing season yielded the best discrimination potential. In addition multiangle texture images were combined to highlight raised berms surrounding individual shrimp ponds.
