Optimising NDWI supraglacial pond classification on Himalayan debris-covered glaciers [PDF]

Remote Sensing of Environment, 2018
The ability of medium-resolution (10–30 m) satellite imagery to delineate the size and persistence of ponds on debris-covered glaciers is a topic of recent interest as it has become apparent through the use of fine-resolution products that smaller ponds have often been neglected.

Comparative Analysis of Normalized Difference Water Index (NDWI) Methods in Continental Wetland

Anuário do Instituto de Geociências - UFRJ, 2018
The remote sensing data, like radiometric indices, represent alternative data generation sources that can help us understand the natural processes that occur in the Pantanal. The Normalized Difference Water Index (NDWI) is a partially known method in the scientific community which makes geotecnologies use. Although, its use and application still causes

Identification of sowing window and sown area of maize and sorghum in rice fallows using multi-source satellite remote sensing

Sains Tanah: Journal of Soil Science and Agroclimatology
Identifying the start of sowing in rice fallows is challenging due to its typical low land agro-ecosystem. Tracking the spatio-temporal shifts that take place during the transition from a wet to dry ecosystem, identifying crops, assessing their extent ...

Divergent Blue Carbon Trajectories in the Yellow River Delta Post‐1976 Diversion: Hydrological Stability and Human Disturbance Contrasts Revealed by Multi‐Source Remote Sensing (1984–2023)

Land Degradation &Development, EarlyView.
ABSTRACT Coastal wetlands are critical blue carbon sinks, yet their spatiotemporal dynamics under environmental change remain insufficiently quantified. Taking the Yellow River Delta (YRD) as a natural laboratory, this study synthesizes multi‐source remote sensing data, including optical and radar imagery spanning from 1984 to 2023, to explore the ...
