The emissivity and Difference Vegetation Index Normalized (NDVI) are important spectral physical parameters in the study of land surfaces. This article aims to analyze the spectro-temporal point of view the influence of NDVI values in the emissivity of the surface of the urban area of Recife / PE. The work is characterized by multispectral Landsat-5 TM satellite images, the spatial and temporal variation of surface emissivity and (NDVI) in the urban area. The methodology involved the implementation of radiometric correction models, atmospheric and SEBAL Algorithm (Surface Energy Balance Algorithm for Land). We used two images referring to the dates 10 June 1984 and 29 August 2007. The maximum value found for the surface emissivity was 0.982 for 1984 and 0.985 for 2007, the minimum value was 0.971 for the year 1984 and 0.970 in 2007, the average and fashion will not suffer change in 1984 0.974 and 0.973 respectively. The Difference Vegetation Index Normalized presented average values of 0.28% in 1984 and 0.23% for the year 2007. According to the results found there was a decrease of 5.1% of the vegetation cover in relation to the year 1984 being the values of higher emissivity in Pina mangrove in 2007.Downloads
