Comparison of Land Surface Temperature Retrieval using Remote Sensing Imagery: Classification-Based versus Normalized Difference Vegetation Index-Based Emissivity Methods

Key Points

• Land surface temperature retrieval demonstrates notable differences in accuracy between emissivity methods.
• Normalized Differenced Vegetation Index-based methods showed a significant error compared to classification-based techniques.
• Assessment using remote sensing imagery across multiple landscapes reveals varied temperature readings affecting the analysis.
• These findings support the need for improved emissivity methods to enhance land surface temperature estimations.
