- •
Uncertainty in urban surface emissivity is investigated based on spectral libraries.
- •
Classification-based method may not be effective for obtaining urban surface emissivity.
- •
Performance of linear spectral mixture model is largely related to the endmembers.
- •
It is necessary to build a comprehensive spectral library of urban materials.
