A mosaic of Northeast China
1995-1997 (combined data)
ESA - European Space Agency
ESA - University of Jena, Chinese Academy of Forestry, ID number: SEMFIFIO9PE
This mosaic image is based on on ERS-1 and -2 combined data and covers a large region of Northeast China. More than 500 radar images acquired between 1995 and 1997 were used to generate the mosaic. In the false colour composite, red corresponds to the ERS-1 and -2 coherence (matching data), green to the ERS-1 SAR intensity and blue to the ERS-1 and -2 intensity difference.
Forests appear in green, agricultural areas appear in orange or yellow, depending on whether the images were acquired in winter or not. Steppe and marsh land surfaces along the Mongolian border appear in red. The green patches in the centre of these regions correspond to the frozen surface of lakes Hulun Nur and Buir Nur.
