| description | The current essay intends to analyze the temporal soil use evolution in the city of Santa Cruz do Rio Pardo – SP through the supervised classification of the satellite images Landsat-5 TM according to the maximum likelihood, as well as verify the mapping accuracy by Kappa coefficient, compare the NDVI and SAVI vegetation indexes in different understanding factors for the canopy substrate and determine the vegetal cover percentage in all methods used on 05-26-2007, 01-07-2009 and 04-29-2009. The Maxver classification showed clearly several spatial changes in the soil use in the considered period. The most appropriated vegetation indexes were the NDVI and SAVI – 0,25 factor, which showed similar values of vegetal cover percentage, but discrepant in respect to the inferred value for MAXVER classification. |

Este trabalho objetiva analisar a evolução temporal do uso do solo no município de Santa Cruz do Rio Pardo – SP por meio da classificação supervisionada de imagens de satélite Landsat-5 TM por máxima verossimilhança, bem como verificar a exatidão do mapeamento pelo coeficiente Kappa, comparar os índices de vegetação NDVI e SAVI em diferentes fatores de ajuste para o substrato do dossel e determinar a porcentagem de cobertura vegetal em todos os métodos utilizados, nas datas 26-05-2007, 07-01-2009 e 29-04-2009. As classificações MAXVER evidenciaram diversas alterações espaciais no uso do solo no período considerado. Os índices de vegetação mais adequados foram NDVI e SAVI – fator 0,25, os quais apresentaram valores semelhantes de porcentagem de cobertura vegetal, mas discrepantes em relação ao valor inferido para a classificação MAXVER. 2011-04-12 2022-03-21T18:21:35Z 2022-03-21T18:21:35Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.ufpr.br/raega/article/view/17416 10.5380/raega.v21i0.17416 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/73977 por https://revistas.ufpr.br/raega/article/view/17416/14028 application/pdf UFPR RA'E GA Journal - The Geographic Space in Analysis; v. 21 (2011) Raega - O Espaço Geográfico em Análise; v. 21 (2011) 2177-2738 1516-4136 10.5380/raega.v21i0 |
