Data product name and description

Satellite ZY1E (ZY-1 02D) was launched on September 12, 2019. it has two cameras as includes Visible Near Infrared(VNIR), hyperspectral cameras. PCI Only supports VNIR data now. The VNIR camera has one Panchromatic and eight multispectral bands, and it has a large view field, with 115 km swath width. It provides great supports in investigating land resources, emergent monitoring and supervising services.

Spectral bands: Spectral range (nm)	Spatial resolution (m)* (spectral resolution)	Maximum image dimensions (Across track x along track, km)	Notes
B02 (Blue): 452 - 521 B03 (Green): 522 - 607 B04 (Red): 635 - 694 B05 (NIR): 776 - 895 B06 (Coastal Blue): 416 - 452 B07 (Yellow): 591 - 633 B08 (Red Edge): 708 - 752 B09 (NIR2): 871 - 1047 B01 (Panchromatic): 451 - 902	Panchromatic: 2.5 x 2.5 Multispectral: 10 x 10	Swath width: 115 (at nadir)	N/A

* Resolution is always nadir position unless noted otherwise.

ZY1E image data is available at one processing level: LEVEL1B. All products are provided with an XML metadata file specific to each. Each data set is either in its own directory or several data sets in one directory.

You can open a ZY1E data set by selecting the *.xml file.

When opening a ZY1E data set, the files read by GDB are as described in the following table.

Processing level	Horizontal accuracy (m)	Description/notes
LEVEL1B	N/A	N/A

Distribution disk files

A ZY1E data set is organized in a specific folder structure on disk. GDB uses this folder structure and the file names to identify the data product type.

Warning: Data sets for this sensor are organized in a specific folder structure on disk. GDB uses this structure and the file names to identify the data product type. Do not alter the folder structure or any file names prior to data ingestion to ensure the image data and auxiliary information are imported correctly.

You can open a ZY1E data set by selecting the *.xml.

When opening a ZY1E data set, the files read by GDB are as described in the following table.

File name	Format	Required	Contents/details
*.xml	Extensible Markup Language	Yes	Key file name, contains data-set metadata
*.tiff	GeoTIFF	Yes	Image data
*.rpb	ASCII	Yes	Rational-function model
*.jpg	Joint Photographic Experts Group	Optional	Thumbnail

Returned data for supported format

The data structure after it is opened by GDB is described in the following table.

Data product	Data returned	Details
MUX (Multispectral)	8 x [16U] raster channels 1 x [ORB] Orbit segment 1 x [BIN] Rational-function model 1 x [TXT] Product annotation	N/A
PAN (Panchromatic)	1x [16U] raster channel 1 x [ORB] Orbit segment 1 x [BIN] Rational-function model 1 x [TXT] Product annotation
