Abstract
The use of satellite images and the indices to determine qualities of the components of the natural environment is enabling today identify their behavior and their evaluation, while facilitating diagnose or predict trends and projections of their behavior. The vegetation cover have great importance for man, hence there are multiple and substantial resources, methods and technologies for the study and conservation of this heritage. The use of indices to show the spectral behavior of the coverage is becoming increasingly common in many researches about the geographical environment. The present study was aimed at determining traced spectral behavior of vegetation cover to a protected area with managed resources; Zapata Peninsula, with temporally period of studies from 2000 to 2012. The temporal behavior from the spectral response vegetation cover, using the enhanced vegetation index (EVI) through the product MODQ13 of the MODIS sensor, was analyzed. As a result, the spectral responses of 17 different vegetation cover available to the area, was obtained. The vegetation cover of broadleaf plantations showed the highest spectral response during the year and the studied period, nude and seminude areas had the lowest response during this research. The months and the years of highest and lowest spectral response of EVI were also identified. Analysis results were obtained with an error of 6%, showing a 94% reliability.
