Since  its launch on 9th, January 2012, China’s first civilian high resolution stereo  mapping satellite ZY-3 has provided a reliable stream of high resolution stereo  image data. ZY-3 produces three line-array stereo panchromatic images (2.1-meter  for nadir,3.5-meter for forward and backward) and 5.8-meter multispectral (red,  blue, green, near infrared) imagery that can be combined in a variety of ways  to accommodate a wide range of high-resolution imagery applications.
The  sample data shall only be used for non-commercial purposes such as scientific  research and education. Data application reports or questions are welcome. Please  contact to Lyu Shanshan from LASAC at lvss@lasac.cn or 905872648@qq.com.
