| Abstract | O Pantanal é a maior área úmida tropical do planeta, onde ocorrem inundações sazonais pelo Rio Paraguai e seus afluentes. Alterações nesta dinâmica influenciam diretamente o bioma. O objetivo deste trabalho é tentar determinar as áreas suscetíveis de alagamento nas regiões de Paiaguás e Nhecolândia (Pantanal Sulmatogrossense), utilizando imagens multitemporais de índices de vegetação (NDVI e EVI) do sensor MODIS/TERRA. Foram adquiridas imagens do produto MOD13 (Índice de Vegetação) do sensor MODIS entre os anos de 2000 e 2005. A partir destas imagens foi realizada a média mensal para cada índice (EVI e NDVI), com o intuito de observar o comportamento ao longo do ano. Em seguida, selecionaram-se as imagens de mínimo e máximo (EVI e NDVI) para cada ano. Com este resultado, foram geradas as imagens diferença (máximos-mínimos). Observou-se que nestas imagens diferença, algumas áreas apresentavam valores negativos, isto é, nestas regiões os valores dos índices de vegetação eram maiores na época da seca do que na época da cheia. Desta forma, deduziu-se que estas áreas (valores negativos), durante a época da cheia se encontravam alagadas (valores dos índices de vegetação menores). Com estas informações gerou-se uma imagem final realçando as áreas prováveis de alagamento para os dois índices em cada ano. Além disso, notou-se que o EVI é mais sensível às mudanças da cobertura e conseguiu destacar a drenagem na região de estudo. ABSTRACT: Pantanal is the largest tropical wetland on the planet, where occurs seasonal flooding caused by Paraguay River and its tributaries. Changes in this dynamic directly influence the biome. The objective of this work is to try to determine susceptible flooding areas in the regions of Paiaguás and Nhecolândia (Pantanal), using multitemporal vegetation index (NDVI and EVI) images provided by MODIS/TERRA sensor. Images from MOD13 product (vegetation index) acquired between the years 2000-2005 were used in this study. With these images the monthly average for each index (EVI and NDVI) was computed, with the intention to observe the behavior along of the year. After that, the images of Maximum and Minimum (EVI and NDVI) were selected for each year. With these results, the difference images (Maximum-Minimum) were generated. In these difference images, it was observed that some areas presented negative values, i.e., in these regions the values of vegetation indices were greater in the dry season than in the flooding season. In this manner, it was implied that these areas (negative values), during the flooding season, were found flooded (lower vegetation index values). With these information it was generated a final image enhancing the susceptible flooding areas for both vegetation indices in each year. In addition, it was noticed that EVI is more sensible to the land cover changes and was able to enhance the drainage in the study region. |
