Data product name and description

Jilin-1 03 video can acquire high-resolution panchromatic images, multispectral images, night-time-light images, and staring video. Staring imaging can provide Level 1A products in timeframe sequence and Level 1B video products. Night-time-light imaging can provide Level 1A products.

Level 1A products are corrected radiometrically and geometrically.

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-1-03B data set by selecting the key file that corresponds to the data type.

When opening a Jilin-1-03B data set, the files read by GDB are as described in the following table.

File name Format Required Contents/details
*_meta.xml Extensible Markup Language Yes Key file name. Use this file to open the data set.
*.tif GeoTIFF Yes Image data, one file for PAN band or all spectral bands.
*_rpc.txt Text Yes Rational functions model data.
*_ENH.tif GeoTIFF Yes Image data, night-time-light image.
*_ENH_rpc.txt Text Yes RPC file of night-time-light image.
