Resumo: The study aimed to analyzed the vegetation from NDVI (Normalized Difference Vegetation Index) dynamics in Eucalyptus dunnii and Eucalyptus Urograndis comparing the NDVI generated from the digital numbers obtained from the conversion to apparent reflectance. The satelite images of TM/Landsat 5 sensor was used. Converting digital numbers (DN) to reflectance values and the calculation of the NDVI were obtained through spatial analysis operations Algebraic Geoprocessing Language (LEGAL). It was observed that NDVI values generated from the reflectances are greater than those determined by the DN. This observed difference is physically justified by the corrections made in the image of some parameters such as the minimum and maximum sensor radiances and mean stratospheric solar irradiance. E. dunnii presented higher values of NDVI when compared to E. urograndis, indicating that this is a useful tool when the objective is to identify the species, facilitating the management of the area.

Para esto, se utilizó las imágenes del sensor TM/Landsat 5. La conversión de números digitales (ND) para los valores de reflectancia, así como el cálculo del NDVI se obtuvieron a través de operaciones de análisis de lenguaje espacial de Geoprocesamiento Algebraica (LEGAL). El análisis efectuado pone de manifiesto que los valores de NDVI generados a partir de las reflectancias son mayores que los determinados por los ND. Esta diferencia observada se justifica físicamente por las correcciones hechas a la imagen de algunos parámetros, como las radiancias mínima y máxima del sensor y la irradiancia solar estratosférica media. El E. dunnii presentó valores mayores de NDVI cuando comparado al E. urograndis, apuntando que esta es una herramienta útil cuando el objetivo es identificar las especies, facilitando el manejo del área.Departamento de Diagnóstico e Pesquisa Agropecuária.
