This map plots the location of permanent wetlands across the globe, as of 2007, using land classification data from the MODIS sensor on NASA's Aqua and Terra satellites. Such datasets, including those from NOAA, NASA, and USGS are often used by habitat specialists to analyze how these areas are changing over time as a function of human activity and natural processes. These features can be seen as points of blue on the map. Other large wetland systems areas can be seen in Russia, Southeast Asia, and Canada. At 75,000 square miles, the world's largest continuous wetland is the Pantanal, which borders Brazil, Bolivia, and ParaguayEducação Superior::Ciências Exatas e da Terra::GeoCiências
