Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/1199The Brazilian coast possesses the second largest continues mangroves area of the world, estimated in 1.38 million along approximately 6.800 km (KJERFVE, 1993). The most exuberant mangroves are found in the north of Brazil (SZLAFSZTEIN, 2000). However, great part of that area, counted as mangroves, it is not in fact mangrove vegetation. The difficulty on the individualization of those two vegetation types, through satellites images, radar or fusion of both, is attributed to the similarity of the spectral response to the same level of humidity in the canopy of the forests. This work aim a better individualization mainly of mangrove vegetation through the tenuous differences in the reflectance levels obtained from Landsat TM 5 image, processed over the Spring Software and based on field data of leaves reflectance from the Bragança coast obtained through a Spectrolino, Gretag MacBeath. The data allowed to characterize the vegetation groups based in their reflectance levels. The vegetal units, herbaceous field, terra firme and mangroves presented reflectance values easily identifiable in the satellite images. However, the mangrove unit presented a clear variation in the reflectance levels.Acesso AbertoSensoriamento remotoReflectânciaManguezaisPará - EstadoCNPQ::CIENCIAS EXATAS E DA TERRA::OCEANOGRAFIATrabalho de Curso - Graduação - Monografia
