Remote sensing data imputation using deep learning for multispectral imagery

arXiv:2605.24003v2 Announce Type: replace-cross Abstract: Remote sensing techniques have been increasingly utilised in aquatic applications in recent years. A common challenge in using optical satellite data is the presence of missing observations due to cloud cover. These data gaps can lead to missed detection of critical events, such as algal blooms, in lakes of high interest to water authorities. As a result, enhancing the completeness of optical satellite datasets is crucial for improving the monitoring and prediction of algal blooms. In this study, we compared a traditional data imputatio

Why this matters
Why now

The increasing availability of satellite data combined with advancements in deep learning models makes this a timely development for addressing data gaps in remote sensing.

Why it’s important

Improving the completeness of optical satellite data is crucial for accurate environmental monitoring, especially for critical natural resources like water, and informing water management policies.

What changes

The reliability and accuracy of remote sensing for environmental monitoring, particularly in cases of cloud cover, are significantly enhanced, enabling better detection and prediction of events like algal blooms.

Winners
  • · Environmental monitoring agencies
