A satellite remote sensing based assessment of urban heat island in Lanzhou city , northwest China
As a promising application, quantitative remote sensing of urban heat island (UHI) could facilitate our understanding of urban/suburban environment and its relationship with urbanization. This paper investigates the urban heat island effect of Lanzhou, China, a densely built up city in a valley, based on Landsat ETM+ image acquired on April 22, 2000, whose spatial resolution is sufficient for m...
متن کاملComparative and Combinative Study of Urban Heat island in Wuhan City with Remote Sensing and CFD Simulation
Urban heat islands are one of the most critical urban environment heat problems. Landsat ETM+ satellite data were used to investigate the land surface temperature and underlying surface indices such as NDVI and NDBI. A comparative study of the urban heat environment at different scales, times and locations was done to verify the heat island characteristics. Since remote sensing technology has l...
متن کاملUrban Storage Heat Flux Estimation Using Aster Remote Sensing Data
As one of urban eco-environmental contents, urban heat island is very significant. Nowadays, the temperature in urban is higher than the surrounding natural terrain, as the result of vegetation cover declining and impervious surface increasing, coupled with the influence of anthropogenic heat discharge. In recent years, it is possible to study the urban heat island and its formation mechanism, ...
متن کاملRemote Sensing Image-based Analysis of the Relationship between Urban Heat Island and Vegetation Fraction
As the relationship between land surface temperature (LST) and Normalized Difference Vegetation Index (NDVI) can not be able to effectively apply after NDVI reached saturation[1]. In this study, the vegetation fraction, which derived from Dimidiate Pixel Model, as the indicator of vegetation abundance has been introduced to analyze remote sensing of the change of urban heat islands (UHIs). Land...
متن کاملPrediction and Analysis of Urban Heat Island Effect in Dangshan by Remote Sensing
Vegetation index (NDVI) was extracted from bi-temporal multispectral images based on the data obtained from Landsat ETM + on 14 th , September, 2000 , Landsat ETM + on 9 th , September, 2004 , Landsat ETM + on 15 th , May, 2008 and Landsat-8 on 21 st , May 2013 for Dangshan County in Anhui Province. Analysis and data extraction was carried out using the ENVI 5.0 software. Normalized values of t...
