Effects of land use and land cover pattern on urban temperature variations: A case study in Hong Kong

, 2020
A remarkable phenomenon in urban climate is the urban heat island (UHI) effect. Based on satellite imagery and geographical and climatological data, this study analyzes the patterns of land surface temperature (LST) and land use/land cover (LULC) in Hong

Analytical study on the relationship among land surface temperature, land use/land cover and spectral indices using geospatial techniques

Discover Environment
Monitoring changes in Land Use/Land Cover (LULC), spectral indices, and Land Surface Temperature (LST) can help to identify the areas at risk for indefensible land use, a low-grade environment, and especially urban heat islands (UHI).

Application of the Dempster-Shafer Theory to the Classification of Pixels from Aster Satellite Images and Spectral Indices

, 2017
In this paper, it is proposed to apply the Dempster-Shafer Theory (DST) or the theory of evidence to map vegetation, aquatic and mineral surfaces with a view to detecting potential areas of observation of outcrops of geological formations (rocks ...

Exploring urban land surface temperature with geospatial and regression modelling techniques in Uttarakhand using SVM, OLS and GWR models

Evolving Earth
Given the climate change challenges, Uttarakhand has become crucial for examining land dynamics and regional climate interactions. This study employed a Support Vector Machine (SVM) for land use and land cover mapping for 2024, achieving 94% accuracy and

Evaluation of the Effect of Urban Redevelopment on Surface Urban Heat Islands

Remote Sensing, 2019
Climate change is a global challenge with multiple consequences. One of its impacts is the increase in heatwave frequency and intensity. The risk is higher for populations living in urban areas, where the highest temperatures are generally identified ...

Land use/land cover change detection and urban sprawl analysis

, 2019
This study presents a proposed application of the Time-Weighted Dynamic Time Warping (TWDTW) method for urban sprawl analysis. Four spectral indices were computed from a long time-series of Landsat satellite imagery, corresponding to 48 scenes acquired ...

Quantifying Urban Warming: A Geospatial Assessment of Land Cover Transformations and Land Surface Temperature in Rapidly Urbanizing Osogbo, Nigeria (2003–2023)

African Journal on Land Policy and Geospatial Sciences
Contexte and Background: Rapid global urbanization heavily drives the Urban Heat Island (UHI) effect through extensive land use and land cover (LULC) transformations. This poses significant climate and environmental challenges, particularly in rapidly

Scenario-based land-use modelling to predict land surface temperature in Jeddah, Saudi Arabia

Academia Environmental Sciences and Sustainability
The rise in Urban Heat Islands (UHIs) is increasingly posing environmental and public health challenges in arid megacities. This study investigates these phenomena by analyzing 35 years of Landsat satellite imagery (1990–2024) to quantify ...
