Service Description: Poyang lake has been shrinking over years. This map shows the comparison of the Poyang Lake areas in 3 different years. I used Iso Unsupervised Classification tool to classify Poyang Lake land cover from the LandSat layers of Setallite images. Then, I used Majority Filter and Boundary Clean tools to remove minor water bodies around the lake. By comparing the final 3 layers showing Poyang Lake in 3 different years, I found the lake area was shrinking in an accelerated speed.
