摘要: The Cerrado is the second largest biome in Brazil, covering an area of about 2 million km2. However, recent estimates revealed that more than one third was already converted into other land cover types. This paper presents a multi-temporal data fusion experiment where Landsat TM image (30 m) fused with series MODIS images (250-500 m). Moreover, simplified method based on Laplacian pyramid concept (SIFuLAP) illustrated. objective to assess ability reflect seasonal patterns Cerrado. In order do that, NDVI temporal profiles were derived from and subsequently compared ones obtained original images. addition, products used attempt improve classification accuracy results showed profiles, images, efficient behaviour improved using as additional information classifier.
