Temporal variation in glacier surface area and glacial lakes in glaciated river basins of Arunachal Pradesh

Journal of Water and Climate Change
Climate change-induced glacier recession has sparked a dynamic transformation of glaciers in high-mountain areas worldwide, resulting in genesis, expansion, and dissipation of glacial lakes that pose a potential threat to downstream communities ...

A Geospatial analysis of Climate Change Impacts: Relationship of Normalized Difference Water Index (NDWI and Land Surface Temperature (LST) in Kumaun Himalaya

Abstract This study presents a geospatial assessment of climate change impacts in the Kumaun Himalaya region, focusing on the relationship between Normalized Difference Water Index (NDWI) and Land Surface Temperature (LST). Leveraging Google Earth Engine, Landsat 5, and MODIS Terra Aqua data, we conducted a comprehensive analysis spanning the ...

Mapping of forest water-stressed changes based on normalized difference water index (NDWI) during 1998-2018 using multi-temporal landsat data [PDF]

, 2019
Forests play an important role in ecosystem and its services by way of regulating the climate of the particular region. However, when the climate turns adverse changes begin to occur that cloud affect the status of the forest.

A Bayesian spatiotemporal Poisson conditional autoregressive model for dengue haemorrhagic fever in Indonesia integrating satellite-generated environmental data

Geospatial Health
In association with cases of Dengue Haemorrhagic Fever (DHF), Indonesia’s Breteau Index has consistently fallen below the national standard of 95% over the past 12 years (2007–2019). Currently, the country relies on survey methods to map DHF spread, but

A new approach for detection of surface water changes based on principal component analysis of multitemporal normalized difference water index

, 2016
Normally, to detect surface water changes, water features are extracted individually using multitemporal satellite data, and then, those data are analyzed and compared to detect their changes.
