Analysis of pasture areas in Brazil using official data and time series of vegetation index

Resumo

The temporal dynamics of pasture areas is strongly associated with the change in economic activity in the area. The impact of this transition, impacts the environmental, economic and social parameters. The evaluation of the temporal dynamics of pasture areas is extremely important for the generation of information to support decisions whether at the local or regional level, public or private. The use of satellite images and geographic information systems is completely indispensable for the evaluation of the dynamics of pasture areas over time, and this is the fact that motivates this research to identify areas of pasture in different years from official maps of land use classification and to evaluate, by NDVI series, which is associated strongly to the biomass of vegetation, the areas of retraction or increase of pasturelan areas, thus identifying the dynamics of land use transition.
