Distribution disk files

A Jilin-1 07B 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.

File name convention

The file name convention of Jilin-1 07B data is described as follows, based on a sample file name of JL107B_PMS1_yyyymmddhhmmss_aaaaaaaaa_bbbb_cccc_ddd_L1_MSS_meta.xml.

Designator	Description
PMSX	Push-scan camera number
yyyymmddhhmmss	Date and time in Beijing time. Beijing time is converted to UTC in GDB.
aaaaaaaaa	Mission number
bbbb	Segment number
cccc	Scene number
ddd	Product number
LX	Product level
MSS or PAN	Spectral 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 Jilin-1 07B data set by selecting the key file that corresponds to the data type.

When opening a Jilin-1 07B data set, the files read by GDB are as described in the following table.

File name	Format	Required	Contents/details
