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.

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.

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 . . .
