Wetlands are biodiversity hotsposts all across the globe. These ecosystems are very sensitive to global change, and long-term monitoring is essential to track changes and trends. Early alert protocols for alien species, water pollution, algal blooms, etc. assist in providing rapid management responses. In situ monitoring requires permanent and extensive sampling in harsh environments. Satellite images contribute to enlarge scales with the need for ground- truth. Drones equipped with multispectral sensors play a very relevant role in upscaling data collected in the field with pixel-derived information. This is the case of the Doñana wetlands, where inundation level, water depth, and turbidity, together with aquatic plant cover, have been mapped with multispectral images captured by a fixed wing drone and used to upscale ground-truth to Sentinel-2 images.
