In this paper

the Tiangong-1 hyperspectral data acquired on April 18

2013

and a Landsat TM imagery acquired on May 1

1985 were using to monitor the wetlands changes in Yellow River estuary. By comparing the classification results of Tiangong-1 hyperspectral data and Landsat TM imagery

the result showed that the decrease in wetlands areas was largely affected by the human activities in the past 30 years

such as beach reclamation and aquaculture. Furthermore

the Tiangong-1 hyperspectral data performed better on wetlands monitoring than Landsat TM due to its higher spectral and spatial resolution.
