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.
