The dynamism of salt crust patterns on playas

, 2015
Playas are common in arid environments and can be major sources of mineral dust that can influence global climate. These landforms typically form crusts that limit evaporation and dust emission, modify surface erosivity and erodibility, and can lead to ...

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 ...

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.

Towards near real-time drought stress assessment in Europe’s temperate forests – comparing remote sensing time series with continuous in-situ tree-level measurements

Ecological Indicators
Increasingly frequent droughts in Central Europe underscore the need for regular forest health monitoring. For decades, vegetation indices like Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) have been used as ...
