ISPRS test data Ziyuan-3-01 2017
Data Sets Region Stuttgart
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.

3. Files
The files of the different scenes can be identified by the last digits before file extension e.g. the scene of file
ZY3_01a_hsnbavp_275102_20121201_183107_0008_SASMAC_CHN_sec_rel_001_12120422639.tif can be identified by 2639 within the available data set
Technical data of the images are available in the *.XML-files (ASCII) as corner coordinates, view direction, sun elevation and azimuth, imaging time . . .
