| Abstract | Spatial distribution and spectral-temporal variations of agricultural lands have been largely analyzed from regional to global scales using the Normalized Difference Vegetation Index (NDVI) derived from images with low spatial and high temporal resolutions acquired by the Advanced Very High Resolution Radiometer (AVHRR) sensor. The Enhanced Vegetation Index (EVI) designed for MODerate resolution Imaging Spectroradiometer (MODIS) sensor onboard of Terra and Aqua spacecrafts reduces the atmospheric and background contamination and also minimizes the NDVI saturation problem over lands with high biomass such as tropical forest. In this paper we investigated the performance of both EVI and NDVI Vegetation Indexes (VI) from 250 m MODIS product (MOD13Q1) for monitoring vegetation canopy conditions in order to discriminate soybean crop from forested and bare soil areas. A thematic map derived from Landsat-TM images was used as reference map to evaluate the VI temporal behavior for the targets of interest. In order to model the spectral-temporal curves for these targets for both VI a fifth-order polynomial equation was applied and a definite integral was then used to calculate the area bounded by the curves. Although both MODIS VI temporal profiles showed almost similar response throughout soybean growing season, we found that NDVI is more effective in discriminating soybean areas from forest and bare soil during the soybean pre-planting period while EVI is more valuable and improves the contrast between those areas during the soybean peak canopy development. | |||
