Finally, the spatial coupling model was used to calculate the spatial coupling degree between NDVI and LST. The study shows that: (1) From 2000 to 2020, the annual NDVI value of the Mu Us Sandy Land was between 0.25 and 0.43, showing a stable upward trend overall, with an increase rate...
Thus, the water bodies and unused land were not considered in the discussion about the relationship between NDVI and LST among the different land use types. Figure 3 NDVI map of the study area. The image was generated by using ArcGIS 9.3 (http://www.esri.com). Full size image Figure 4...
their vegetation and built-up areas. Everyone of them works on his own and one can see the difference through satellite images. In this research, the relationship between the LST, the NDVI and the NDBI
Two methods, the ordinary least squares (OLS) regression and multiple adaptive regression splines (MARSplines), were used to find the relationship between NDVI and LST. The strength of the relationship was assessed via the coefficient of determination R2 (Table 3), which indicated that a portion...
and planning of land resources. The present research is based on a study of four decades: 1991, 2000, 2010, and 2021. There are various mapping techniques used for the assessment of the relationship between LULC and LST, SAVI, and NDVI. Show the trend variation in NDVI, LST, and SAVI ...
Compared with the relationship between the NDVI, DEM, and distance from the water body, the negative correlation between the NDMI and LST was stronger and more stable and had the greatest effect on LST. These insights improve the understanding of the land change consequences on the temporal ...
This nonlinearity and the platform dependency suggest that NDVI may not be a good indicator for quantitative analyses of vegetation (Small, 2001), and the relationship between NDVI and LST needs further calibration. More quantitative, physically based measures of vegetation abundance are called for, ...
Chun and Guldmann (2014) explored the potential relationships between the land surface temperature (LST) and five urban characteristics captured over regular grids, i.e., building roof-top areas (BGFA), normal different vegetation index (NDVI), solar radiation (ASR), sky view factor (SVF) and...
(2) analysis of the spatial distribution of LST and its relationship with LULC and Normalized Difference Vegetation Index (NDVI), and (3) analysis of relationship between LST and the population density as well as its impact on energy consumption and the health of residents in the study area. ...
According to OLS findings, there is a negative association between NDVI and LST values, much like in other papers, and a positive correlation with NDBI and LST values (Guha et al., 2018; Khorrami & Gunduz, 2020) (Table 5). The closure periods have lower NDBI coeffi- cients than ...
