ZY-3 Satellite High Resolution Stereo Image

ISPRS test data Ziyuan-3-01    2017

Data Sets Region Berlin

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 . . .

                                          width    height    (columns    lines)
bwd = backward, pan        3.5m GSD   24513 x ~19997 pixels fwd = forward, pan            3.5m GSD   24513 x ~19996 pixels mux = nadir, color, 4 bands  5.1m GSD  8820 x ~8786 pixels   (blue, green, red, NIR) nad = nadir, pan              2.1m GSD   24513 x ~23996 pixels

 

for any image usually 8 files are available as:
