| Resumo | This paper demonstrates the applicability of RADARSAT stereo-images for the interpretation and measurement of some characteristics of the Brazilian tropical rain forest. Clearing boundaries, vegetation cover and canopy heights were qualitatively interpreted and quantitatively measured on a fine mode RADARSAT stereo-pair using a PC-based softcopy stereo workstation. Since no ground truth was specifically acquired for this project, the validation of the results is realized in two steps using previous research studies of the same site. The clearing boundaries were first overlaid on a previously orthorectified Landsat-TM image to verify their planimetric accuracy and the interpretation of the vegetation cover. The planimetric positioning error of 30 metres for the clearing boundaries was mainly due to the accuracy of the input cartographic data. Larger errors were a result of the deforestation and regeneration between image acquisition dates, the dominant scattering regime from the forest and the misinterpretation of SAR backscatter The computed canopy heights were then compared to an existing vegetation map, which described the tree species and their characteristics of each class. The results in canopy heights were generally consistent and a good representation of terrain reality. With few exceptions, a mean height variation of about 5 metres with the 11 expected" canopy heights based on previous studies was obtained. In the context of monitoring the Amazon forest in Brazil, these results based on radar stereo geometry show promise as a complementary tool to traditional methods based only on radar radiometry. |
