Fusing Time-Inconsistent Sentinel-2 Images and High-Resolution Remote Sensing Images

Runmin Dong, Haohuan Fu

Abstract: One of superiorities of satellite imagery is quickly monitoring the atmosphere, land, and ocean at a large scale [1], [2]. However, due to the trade-off between spatial coverage and resolution, satellite images with a broader range usually have a lower spatial resolution [3]. Owing to the advancement of satellite remote sensing, multispectral images can now get a high resolution such as 10 m, benefiting various applications including land cover mapping, water resource management, and agricultural monitoring. Furthermore, on account of high revisit frequency (every 5 days), relatively high spatial resolution (up to 10 m), and free access, Sentinel-2 imagery has received widespread attention and become an important resource for earth system studies [4].
