Este trabalho mostra os resultados iniciais de uma pesquisa sobre classificação de imagens multiespectrais considerando feições de textura, aplicada ao mapeamento da cobertura da terra, com ênfase na separação das classes de cobertura vegetal. Para tanto foi efetuado um levantamento bibliográfico e estudo sobre o assunto, que está resumido na parte inicial. Na seqüência relata-se a parte prática, onde foi feita a classificação multiespectral da imagem LANDSAT-5 TM da Ilha de São Francisco do Sul-SC, utilizando o algoritmo de classificação Máxima verossimilhança. Para testar as potencialidades das feições de textura foram efetuadas quatro classificações distintas para obter as mesmas informações agrupadas em dez classes. Na primeira etapa foi efetuada somente a classificação multiespectral, nas outras foram consideradas feições de textura e classificação espectral. Classification of LANDSAT TM’s multiespectral images and texture features: land cover mapping Abstract This paper shows the initial results of a research regarding multiespectral image classification using texture analysis for land cover maping. A bibliographic review was conducted wich is disposed in the first part of this work. Following this, a classification of the LANDSAT TM image of São Francisco island, SC, was performed using the Maximum Likelihood Method. To test the texture analysis potentialities, four distinct classifications were performed to obtain the same informations grouped into ten classes. In the first one only a multiespectral classification was performed, and in the other three the texture analysis was considered.

Fifteen 1: 250000 and one 1: 1000 000 scale Landsat Thematic Mapper (TM) image mosaic maps are currently being produced of the West Antarctic ice streams on the Shirase and Siple Coasts. Landsat TM images were acquired between 1984 and 1990 in an area bounded approximately by 78°-82.5°S and 120°- 160° W. Landsat TM bands 2, 3 and 4 were combined to produce a single band, thereby maximizing data content and improving the signal-to-noise ratio. The summed single band was processed with a combination of high- and low-pass filters to remove longitudinal striping and normalize solar elevation-angle effects. The images were mosaicked and transformed to a Lambert conformal conic projection using a cubic-convolution algorithm. The projection transformation was controled with ten weighted geodetic ground-control points and internal image-to-image pass points with annotation of major glaciological features. The image maps are being published in two formats: conventional printed map sheets and on a CD-ROM.
